Mood-tagging and why it won't work
2007-11-08 20:07:32
The topic pops up again and again - describing the "mood" of music. The "demand" appears to be there. At least software-technologically however, implementations aren't available. I also think i know why they aren't available. Its not mainly because of lack of interest, but instead because implementers as well as users lack the abilities to make it work efficiently. The main problem with that is the user-side.... it just needs one gifted implementer to create the tech - but every single user needs to be able to understand and use it. To avoid various misconceptions beforehand, some definitions first... With mood-tagging i mean describing the mood-relevant "properties" and "characteristics" of music. I do NOT mean "listening situations" like i.e. "chill out / relaxing" or "party". Neither do i mean singular classifications like "trippy". What i mean with mood-tagging is identifying the "components" of which moods consist and then rating tracks according to those components. In other words, i'm not talking about the dish but about the ingredients. To consider such a system to "work efficiently" i demand the following requirements to be fulfilled: A user with thousands of tracks across many different genres, must be able to rate those tracks without too much effort. Afterwards, he must be able to build playlists just by looking at mood and genre tags, and get consistent results (low amount of "unsuited tracks"). The problem now is quite simply, that you need a very introspective, self-understanding and musically experienced user to rate tracks efficiently and consistently regarding their mood. Even something as simple as "energy".... so, if a track is more relaxing or stimulating... would overstrain the ability of most users, because it is not simply a matter of tempo, and it requires quite a bit of understanding if you want to get it right consistent across genres. In the case of "energy", most users would probably be able to consistently rate on a 1-3 scale, but not more. With other more psychological aspects like "uplifting" and "depressive" it gets way more complicated. To get to the point: most users are not able to consistently mood-rate thousands of tracks across many genres - mood-rating music has way more to do with consistently understanding ones own feelings and perception, than it has to do with rating songs. However, that this most probably wouldn't work for most people, isn't even a problem. Why? Well, because most people never actually wanted mood-tagging. Mood tagging isn't a solution - it is just a means. A means for what? Well, a means to easily find suitable music for certain OCCASIONS (listening situations). This what most people actually want. But unless you are a VERY varied person, you do NOT need mood tagging for easily finding suitable music for a certain occasion. All you need for that is a fieldname like i.e. "occasion" and a fixed amount of values like "dance", "relaxing", "party", "lunch", "work" etc. - then just apply those labels consistently across your music, et voila, you can now easily select matching music for your favorite listening situations - especially if you combine it with genres. - Lyx
