[Vorbis] Adviced way of tagging music

[Ivo Emanuel Gonçalves]

There has been recent work on an advanced metadata format for Ogg
content (music and everything else) named M3F[1].  None of the Xiph
tools currently support it, though, so I would say for now stick with
Vorbis Comments, unless of course you (or someone else you may know)
would like to expand applications in that direction.
