i listen to the original F-Zero soundtrack. Here's what I did:
I downloaded the SNES audio files here:
http://snesmusic.org/v2/profile.php?...t&selected=840
extracted the files with winrar, edited their lengths to be about 4 min long each (you can edit them in winamp with SNESAmp if they are extracted and not read-only), shortened the fade-out to 3 seconds, and rebuilt the archive with winrar.

used SNESAmp in winamp to create .wavs of the songs (using high-quality output in SNESAmp; it makes the bass sound better, IMO):
used LAME to encode the files to 192 VBR mp3s (lame -V 2 --vbr-new):

this process can be done with any SNES game
