WikipediaPerhaps an obvious pick, but oh-so-justified at that. Axl Rose, for all his riot-inciting, fan-punching, girlfriend-beating behaviour, is one of the most exciting, talented and engaging frontmen of all time. It just so happens that he's also a bit of a tool. For all those points touched upon (jumping into the crowd to take a fan's camera in St. Louis before causing a riot, assaulting several girlfriends and even accusing them of being sisters in a previous life that were now back to kill him...), his attitude towards his fanbase is perhaps his most notable act of douchebagery. Rose turns up - at best - an hour late to almost every gig he plays, he delayed the 'Chinese Democracy' album for almost two decades and cost his record label $13million (it wasn't worth the wait or the cost), as well as engaging in online bullying towards fans that dare to call him out on such childish behaviour, before proving to be so unprofessional that any other band member worth talking about has long since walked away from him. Guns n' Roses, at their prime, were the most rock 'n' roll band going; young, dangerous, and incredibly gifted. But after Slash, Duff, Izzy, and the other 384 former band members went on to happier pastures, Rose got into homeopathy, employed a 'guru' named Beta, grew dreadlocks, then cornrows, and started employing men with names like 'Bumblefoot' and 'Buckethead'. Nice. 20 years after debut GNR album 'Appetite for Destruction' was released, the band were inducted into the Rock 'n' Roll Hall of Fame, offering Axl a final chance to seek retribution, patch things up with Slash and co., and actually show people that he was capable of doing decent, human things. He didn't turn up.
