Next site: djshop.de

Here's a script for the DJshop downloads: djshop.boo. The way the site is organised, it would have to be a separate script for CD or Vinyl searches. As you pointed out, Vinyl has the watermark on the images, and the CD results I found were pretty poor - 300x300 at most. Unless they have covers for CDs that aren't available elsewhere, I don't think 300x300 CD images are worth having another script for.

noob question:
I have a few thousand albums to grab covers for, and on the first try it wanted to grab a cover for every song :/
Not good.
All the albums are saved in their own directories and 98% have 'artist - album' directory name.
How do I go about it?
Also, what is the best way to automate it as much as possible?

Should I first find/run a ID3 tag cleaner (tags on the mp3's are iffy at best)?

Thanks

If your tags are iffy, but the directory naming is 98% good, then use file path pattern matching in the File Browser (click the Options link in the File Browser window to see this option). The pattern you want would probably be "\%artist% - %album%\." (no " marks). It's also a lot faster than using tags.

To automate as much as possible, you'd want to use Automatic Image Downloading, but I'd recommend you try a few one at a time first, to get a good idea of the sorts of results you want, so you can choose the right source(s) and filter criteria to use before kicking off a big automated job.

Good luck!

AlexVallat it's possible to make searche in ebreggae.com in the stock items. For example Trojan Roots Box Set AAD found good, but it can't find Trojan Reggae Duets Box Set because it out of stock. I can find it only in google with this string "Trojan Reggae Duets Box Set site:ebreggae.com"

I've had a good look around the ebreggae site and can't find any way of getting it to include out-of-stock items in the search results, sorry.

I am not going to have google do the searching for this site, as it looks like google prevents access if you use it too quickly or too much, so having multiple simultaneous searches (which would be the case if I had several scripts all using it for their searches) would likely trigger their protection mechanism.

Thank you! That set me off in the right direction.

Though my directories are messy, but not that bad (I have no idea why people cram that much stuff in a directory name anyway).
I guess a little perl regex will go a long way to clean it up.

I have a beef with the auto-downloader interface.
It's cumbersome to see at a glance what cover is for what album. I had to click on every album to see it's cover.

It would be much better to have the scanned album name close to the downloaded one. Ditto for correcting, I'd rather have to click/right click on the downloaded cover to have the search pop-up, then go through the list.

Unless I've misunderstood, this is already possible. If you right click on one of the results in the bottom area automatic image download window the bottom entry on the menu should be "Search in New Window", which is the same command as appears when you right click one of the results in the list area.

Alex, there's a problem too with removing the "170x170-75." from the URL with the above example album, the picture doesn't exist! Only the "600x600-75." is found. So you should first try to remove the part and then fall back to the "600x600-75.", and if that doesn't exist, the original 170px.


Hey Alex and Akkurat.
If removing the "170x170-75." part from the iTunes-URL does not work, try ".tif" instead of ".jpg". This should solve the problem.

some of the iTunes images are tifs others are jpgs. the rescaling function (i.e. 600x600-75 or 170x170-75) always returns jpgs.

Great find! I'll still leave the 600x600 rescaled image in as a last resort, but will try .tif first.

Here are the updated scripts:
itunes-google.boo
itunes-bing.boo

I only know of one result which used to return a rescaled jpeg and now returns a (sadly still only 600x600) tiff, so if anyone knows of more examples to test them with, please let me know how they get on.

Also, has anyone been trying out the iTunes/Bing script? I've found a couple of cases where Bing hasn't been able to find an album that Google has, for some reason, but also Bing has never stopped working because I've done too many searches on it too quickly. I'm not sure which one to choose.

Hey Alex,
here is an example for a larger tif from the iTunes Store:
http://a4.mzstatic.com/us/r1000/048/Music/...zi.cyomhscs.tif

I had some cases where google didn't find an album from the iTunes store. You may help yourself going the "manual" way:
Use iTunes to search and browse in the iTunes store, instead of using the google search. If you've found the album you're looking for, right click on the image and select "copy link" and paste it into the adress field of your internetbrowser.

I have another suggestion:
Some Amazon images are zoomable and return really large Albumart compared to amazon's standard 500x500 pictures.
You may adress the Zooming pics using the "_SRCM_" extension as described here:
http://aaugh.com/imageabuse.html

Here are two examples from "amazon.de" (i.e country code is set to ".03."):
http://ec2.images-amazon.com/images/P/B004...A.03._SCRM_.jpg
http://ec2.images-amazon.com/images/P/B004...Y.03._SCRM_.jpg

Is it possible to adapt the Amazon scripts to adress also the zooming pictures?

Hmm... I wonder if whatever web service iTunes uses for searching is exposed anywhere - it would certainly be nice to be able to search iTunes without getting a separate search engine exposed.

That is a very interesting page. I have created an updated version of amazon-common.boo which tries to get an SRCM image, and if that fails, falls back to an SCL (large - usually 500x500ish) image. From a bit of quick testing, SRCM's aren't that common, but there are certainly a few around.

If you replace the existing amazon-common.boo with this one, then all amazon scripts will be using the new system. If you notice any problems with it, please let me know. Otherwise, I'll roll it out as an upgrade for the official amazon script in a few days.

Thanks,

Alex

Good news, it is! This means I can do a pure iTunes search without involving Google or Bing, and involving far less server round-tripping as it doesn't have to fetch the iTunes web page for each album to get the thumbnail. I'm not usually much of a fan of Apple's, but I've got to admit, this is the way an API ought to be done.

The downside is that it only searches the US store. You can choose to search a different one, but not to search across all stores, which is a shame.

Try it out here: itunes.boo

Great work! The new iTunes script is much faster than the Google/Bing search! Moreover it finds more than one album in contrast to the old Google/Bing method (that tends to find a lot of duplicates). The new Amazon script also works fantastic.
From now on this program is definitely the best album art downloader of the world!

This could explain why I still cannot find some covers from the german iTunes Store. May you please offer different iTunes scripts for different countries?

That could be done, in a similar way to the way Amazon is handled now. The only difficulty is in knowing which countries to do. The only list I can find is the main apple site country chooser: http://www.apple.com/choose-your-country/, but I doubt they have different iTunes catalogues for every one of those. If they do, that would be a lot of scripts to make available!

I'm glad the new amazon script is working out so far, thanks for letting me know.

Hmmm. My iTunes gives me 123 different countries to choose. It would be nice to have a dropdown menu or a selection page, to choose the store(s). Or even better: The scripts beloging together may be grouped in the sources list (i.e. the Amazon/iTunes/Coverlandia/LastFM...)?

Yes, that's the documentation I used for the API. It's a shame the API doesn't allow you to choose "any" as the country to search. The issue, as I see it, is not figuring out what the country codes are, but rather that I'm not going to ship 123 iTunes scripts with AAD. You just know people are going to install all of them and search the whole lot each time, swamping results from any other source.

Unfortunately the current script architecture doesn't support having custom UI for a script, so I can't put in a dropdown picker to let you choose the country you want to search. Even if it did, that system wouldn't allow you to search multiple countries - I imagine people might well want to search two or three countries, so I'd prefer a system that allows you to have a multiple choice of countries to search.

Where did you get that list from, originally? I've just knocked up a bit of code to run through an produce iTunes country-specific script overrides (like the Amazon ones), and found that too. So I put in a check to do a quick search (for "_") and see if anything came back at all. The ones which I found to work are:

Code: [Select]
Australia (AU)
België/Belgique (BE)
Canada (CA)
Denmark (DK)
Deutschland (Germany) (DE)
España (Spain) (ES)
France (FR)
Greece (GR)
Ireland (IE)
Italia (IT)
Luxembourg (LU)
México (MX)
Nederland (Netherlands) (NL)
New Zealand (NZ)
Norge (Norway) (NO)
Österreich (Austria) (AT)
Portugal (PT)
Schweiz/Suisse (Switzerland) (CH)
Suomi (Finland) (FI)
Sverige (Sweden) (SE)
UK (GB)
Japan (JP)
What I could do is not include them with AAD or through the normal online updates, but have a wiki page where you can download any of them you want. You would need the original itunes.boo (which searches the USA store), then as many of the country-specific overrides as you wanted. I don't want there to be any way for you to accidentally end up with all of them, though. If you really want every single one, you'll have to explicitly download them all.

Script updates
I've just published through Online Updates the updated Amazon scripts (using thomian's info), DJShop, and iTunes (using iTunes search API).

Country-specific overrides to search stores other than the main USA one are available here: iTunes Country-Specific Searches, but will not show up in the online updates "new scripts" notification, or be bundled with the installer. They depend on having the main itunes.boo script installed, and only that main script will need to be updated if future changes are required.

The iTunes/Google and iTunes/Bing scripts are now deprecated. They are still available for download (including the latest changes to support full-sized tiff images), and will continue to work until either iTunes, Google or Bing change their site layout, but will not be included in online updates, or future installers.
