Windows Media Player can play MP3s

You shouldn't have a problem playing MP3s

If you would like a stable, fun and advanced MP3 player - visit http://www.winamp.com - use Winamp. It plays MP3 WMA AVI and streams popular shows and tutorials for sites such as Deviantart.

It's safe and secure, it'll also be set as your Limewire's player (when you execute the file insted of preview)

Have fun!
