- Is Masstagger the best way to import 30k song stats efficiently
Yes. But you might need to break up the operation. I know that masstagger can handle 10,000 lines at once, but I'm not sure of the max no. of files you can do at one time. Someone else might know. If it can't, just create 3 playlists of 10k files each and that would certainly work. Just be methodical.
You want to use Tagging > Manage Scripts > Add > "Input data (one line per track)"
When I did something similar I used:
%PATH_MATCH%,%ADDED_TIMESTAMP%,%FIRST_PLAYED_TIMESTAMP%,%LAST_PLAYED_TIMESTAMP%,%PLAY_COUNT%
And the per line data I added was like so:
D:\path\filename.mp3,129384058953900000,129384058953900000,129384922953900000,1
I did this in Excel > CSV [then renamed CSV to TXT which gets rid of the columns and gives just rows of data which is what you want] and then copied from notepad to foobar2000's masstagger.
The purpose of creating a field called path match, was so that I could check later that the stats data was applied to the right files. That can be quite useful, as without doing so, if you've made a mistake with the order you may not realise or have a way to check.
- Are the dates calculated using
A file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 A.M. January 1, 1601 Coordinated Universal Time (UTC)
Yes.
