no, he was already in prison when he did this track? (I think, it sounds like he's rapping from a prison phone - which he did I'm sure you know)
Personally I always thought it was this one song he did with brotha lynch(?). I remember this one song from brotha lynch where he raps about sticking a gun up a vagina and "boom, pussy goes all over the room"... but I don't even think that's the song. These dudes were really fucking sick and crazy in a lot of their songs. I'm not sure I've ever heard the song with the details that got x-raided busted for that murder... they certainly rap about sick shit on the regular. Maybe it's out there and we just don't know? Wiki, police, nobody will probably tell us which song it was. All we know is that lyrics in one of his songs led to his murder conviction. It might have been an unreleased song for all.
