HybridFan is right. I use ogg files for my SmartPhone because I have only 256 Memory Card, it only holds 60+ songs, but with ogg, I can hold up two times 2 using 64 Kbps compression. 64 kbps is still good when you convert it from the Original Source. Mp3Pro is also nice.

remember that it's not good if you convert a Mp3 to Mp3pro or Mp3 to ogg.


by the way, you can download Vorbis encoders ogg here:

vorbis.com

Mp3Pro is with MusicmatchJ ukebox or Adobe Audition 1.5
