Why music ID resolution matters to every music fan on Facebook

The world of classical music is even more complicated. The same orchestra and performers may record the same piece of music multiple times in different locations or years or with different conductors. All of these things make the identification of a particular piece of music even more difficult.

Right, ISRC is somewhat useful for glue but is not in wide enough use that it covers the world of music. It also reflects "recordings" not "songs" which actually cause a lot of resolution issues (radio edits, clean vs. explicit and etc.) It also does not help anyone resolve artist names like "The The" when their stopword list turns that into an empty query :)

The exact same track can have multiple ISRC's due to being represented by different labels in different regions.

That was quite an interesting read. I felt somewhat vindicated at the end of the article when the author mentioned that audio fingerprinting is a potential solution to this problem. While reading about the various issues created by matching songs based on names and artists, I immediately started thinking about how one might instead identify songs based on their acoustic properties.

Having looked into it a little bit (i.e., having read the wikipedia page about acoustic fingerprinting) I see that there are quite a few implementations in existence and that they appear to be fairly reliable at identifying songs based on the fingerprints -- which is really cool, first of all. Taking that for granted, it seems like facebook could solve its problem by creating a comprehensive database of songs which its music content partners offer.

In particular, I'm thinking of a database with entries containing an audio fingerprint, data about the artist, song, album, and so on, and links to the song on each of the partners' services. Then it would be possible to initially loop through each song offered by the partners, generate an acoustic fingerprint, check if it exists in the database[1], and then add a new record or add a link to an existing record as appropriate. This would be a huge process, of course, but afterwards you'd only have to perform this step for new songs, and you'd ultimately end up with a very impressive database of music IDs.

Anyway, that's undoubtedly a simplistic idea of what could be done and I'm surely glossing over some major obstacles, but I enjoyed indulging in some wishful thinking about it all the same.

[1] As I mentioned, I don't know anything about acoustic fingerprinting, but intuitively I can imagine it's probably not as easy checking if that fingerprint "exists" in the database. More likely, you'd have to check how similar it is to existing fingerprint and choose some threshold above which it's sufficiently likely to be the same song.

I think this would be a great time for Facebook or some large company who is interested in music identification to start using the MusicBrainz database. They already have a huge database and most of them have an acoustic hash as well.
