Maybe they can't spare the computer power to create an acoustic signature? How complex is the algorithm anyway? By the way, I agree that the same song can be sung by the same artist in multiple versions, especially if it is a "signature song" for the artist. Just Acoustic vs. Rock beat can totally be different, and they are both worthy of having in your music library and not wantonly purged because the metadata is the same.

The acoustic signature would be generated by the client, then matched by the server. A bit more work than comparing tags, but not particularly onerous.

  Not onerous? For what size libraries? For your iPhone? For a 3 year-old iPod Touch? My iPhone 5 was trying to process photos in the background last night and my Twitter app stopped responding to touches. The keyboard was lagging by 30-60 seconds. Are you sure acoustic signatures will not be particularly onerous?

    iOS devices never need to generate those signatures, as there's no way to add new tracks to your iTunes library from them.
