Question

so i'm trying to upload music that I've purchased thru Itunes and yahoo on a personal site. The instructions on site tell me to type in artist name, song and browse to upload mp3 music. Whenever i browse to upload song, I get an error message that file must be an mp3 file???? All of my songs are saved to my music file and are on my Ipod. How do I get these songs from either places omto the personal site? The instructions also say to browse to the mp3 on my machine????????????

Please Help
