Each song may be included in an arbitrary number of collections (at least one). A song can also be directly added as OP/ED for an anime (also stored: first ep the song was used in). A song is related to files. Each file can contain one or more songs (i.e. full CD image). And each song has lots of files. | ||

Files are initially not linked to any songs, albums or artists. Once known to AniDB a file can be manually linked to a song via the web interface or an AniDB client.

* (EXP) that's pretty similar to music brainz, being free definitely has some advantages. However, unfortunately it seems as if they're not offering any indexing server which would assign unique ids (like musicbrainz's TRM ids) to songs based on acoustic fingerprints. That means we'd have to do that ourself. Storing lots of ~500Byte fingerprints (which are not 100% equal for different files of the same song) and doing the loose matching would be quite demanding for the server. That could of course be handled by a separate server, but I wonder if it is really a good idea to duplicate existing services in such a way. On the other hand one of the main problems with music brainz is that they regularly purge old/rarely referenced songs from their database. Which could give us some real troubles for anime OSTs. If you try it, you'll notice that their coverage of anime OSTs is very poor. | * (EXP) that's pretty similar to music brainz, being free definitely has some advantages.
