MP3 Sound Files

I have PDA for since almost 3 years, my ultimate purpose for owning PDA was to use for reading Washinton Times news, using Bible software, and playing solitare/hearts games. But now, I am using it for playing MP3 and WMV files by using Windows Media Player. It works.

I am not familiar with MP3/WMV free audio files out on the internet. I am trying to find more clean MP3 files.

So far, I found these sites for downloading MP3 files:

Christian MP Free

Christmas MP Free

Free Solo Guitar

Free Solo Piano

Anyone know any other good free legal MP3 or WMV sites without userid and password? Please post at the comments box. Thanks!
