That youngest argument is neither here or there considering B.G., Wayne, Turk, are about a year and some change apart. There wasn't much difference in age among them whereas Juve is like 5-6 years older than them. And LOL his placement on Juve's biggest song is him saying wobble d wobble and drop it like its hot. Mannie Fresh is also featured. And that song would still be Juve's biggest song with or without Wayne.
During their hey day, Wayne had like two placements: a remix of Young Bloodz "U Way" (his first outside CMR) and a feature on Nelly's debut. Neither of these happened because either artist thought he was the best on the group or their favorite. According to Nelly, Wayne was the only one who believed in his music and was the only feature who agreed to be on the album. Young Bloodz talked about being cool with Wayne and they did the remix.
