Comment 5 for bug 502474

1. I can't see the relation between this bug and the upstream bug related
2. I use to read a lot of complaints from devs saying that there's no solution that would be good for all file formats (mp3, ogg, wav, wma). So I say: who cares? Not an user as me, every step towards the implementation of this proposal (or in my personal perspective, the solution of this bug), is very welcomed even if not complete.
3. For mp3 there's a standard solution: see the POPM field in http://www.id3.org/id3v2.4.0-frames
