Here is a link to a good mp3 player that works on the netBook Pro
http://www.winampaq.com/new/download.html
I used the Nexio 160 link and it loads fine. When you run winamp you get a load DLL error, just okay this and Winamp will run ok. Sometimes I find it will not close propely but most of the time its okay. You can use Winamp v2 skins as well.
