I find the audio on the Kaiser to be excellent - a definate improvement over my old Blue Angel.
For example, when I have TomTom going as well as music, the voice directions mix in perfectly with the music - no crackles, no distortion etc. In fact, at times we miss the directions cause they mix in so well we think it is part of the song :P
I use Pocket Player
as it plays WMA and has a much better interface than windows media player - all the functions can be controlled by keys, plus you do not need to make playlists, it will auto scan the tags and build a database from that.
