I use Ogg Vorbis and encode all my music at 64kbs for my Victory. The sound quality is comparable to 128-192 kbs mp3 and uses a minimal amount of storage space (about 1-2 Mb per song).
I use Goldwave to convert my music and JetAudio as my media player. Not sure, but Audacity might work to convert mp3's to ogg.
