GSPlayer is a small, open-sourced MPEG audio player for PocketPC devices. Software allows playback of ShoutCast streams, MP3s, MP2s, etc. GSplayer can be windowed into a small window that can float on top of other applications (and can be obviously minimized or ran in the full screen), which comes handy when you browse through ShoutCast radio station listings, etc with Pocket IE. Excellent little software that doesn't take much resources and, best of all, is totally free.
