Running on Java, aTunes is a multi-platform application that manages your library of songs. Do not let the name resemblance fool you, according to the site aTunes will only read songs from your iPod but not write to them.
The program can play pretty much all the major audio track formats (mp3, ogg, flac, wma, and more). The playlist functionality, podcast management, and cd ripper tools look to be pretty solid.
Honestly, I don’t like applications running on Java since they tend to be very sluggish. But, I like the fact that aTunes is cross-platform and can be a very nice program for those constantly working between different operating systems.
