I've wanted to do something like that in the past, myself. The solution
I was considering (though I never actually got around to implementing
it) was a FUSE-based filesystem. The idea would be that files would be
stored in, say, a hidden, top-level directory and their ID3 tags
scanned. The filesystem would then make the files available in, say
"by-genre", "by-artist", "by-title", "by-album" and so on folders.
Possibly with the ability to have multiple layers so you can get 
"by-artist/Queen/by-album/Greatest Hits II/*.mp3"

In other words, listing a directory would provide a live filtering of
that available files, depending on the directory name. In an ideal
world, changing the filename/path would alter the ID3 tags and vice
versa.
