Free MP3 Players
In most situations, you should be able to simply click on the song and it should load through your software on your computer, because most computers have either Windows Media Player, Real or Quick Time loaded already.
If your computer does not load these songs, go to any of these sites for a free version for a media player that plays MP3's.
