I'm 18, hate rap music and really have no affinity for Lil Jon whatsoever.. But I do interact with other people my age that do.
He helps recruiting. Period.
If you think he's vulgar, then get a clue about what the rap industry is really like. Look up artists like Tyler, the Creator's song "Yonkers" or "Tron Cat". Or maybe Earl Sweatshirt's song "Epar". What's that spell backwards? Yeah, that's what the song is about.
Lil Jon is a kitten compared to these guys. So, please, get the **** over it.
