Wayne Number

Alright, I already said something about this in chat, but since that's hardly permanent, I'll expand upon it here. This concept is similar to a Bacon Number, which is the number of movies it takes to link an actor to Kevin Bacon. A Wayne Number is the number of musical collaborations it takes to link a musician to rapper Lil' Wayne. Samples don't count unless they've been rerecorded specifically for the song they're in. So Dido's chorus on "Stan" would count. but not the Daft Punk sample in  "Stronger".

Examples

 * Eminem has a Wayne Number of 1, having appeared with Wayne on his song "No Love"
 * The Gorillaz have a Wayne Number of 2, having appeared in "DoYaThing" with Andre 3000, who has collaborated with Lil Wayne on "The Real Her"
 * Devo have a Wayne Number of 3 having performed with Josh Freese, who collaborated with Weezer for their album "Ratitude", which featured a guest spot from Lil Wayne in the track "Can't Stop Partying"
