RAP LYRICS

My oldest son has just turned 12 years old and is started to take interest in different types of music. Lately his biggest interest is rap songs but how do you know when the song is ok for a boy of his age? I have been looking through a great website that offers Rap Lyrics, so I can take the time to read the lyrics to some songs to know if it is ok for him to be listening to. I think this is great! Check out the Kanye West Lyrics to see for yourself.
