Linux instead of Rockbox (was: Some topics related to MP3 players)

You can have multiple genres in both Ogg Vorbis and MP3. In Ogg Vorbis it's done by having
multiple tags with the same name and different values, in MP3 it's a convention (but supported
by some programs) to have a comma separated list of values on the genre tag, IIRC.

Of course, few people care about this. The good thing about using Linux or any other
all-purpose OS for an audio player is, that you can choose between a couple of audio playing
applications matching your desires. If no program fits your needs you will find one in your
preferred programming language to hack. This is harder with a specialised system with a
smaller user and developer base, such as Rockbox (which I actually find very impressive
compared to any proprietary MP3 player system software).
