It was announced today that Rob Zombie and Megadeth will be co-headlining a spring 2012 U.S. tour. But we want to know which act should get to play the final set?

Rob Zombie is a rock superstar, having fronted the band White Zombie and continued his success as a solo act. With his signature White Zombie hit 'More Human Than Human' along with his solo hits such as 'Dragula,' 'Living Dead Girl,' 'Never Gonna Stop' and 'Foxy, Foxy,' among others, Zombie has been creating memorable music for a quarter century.

Megadeth, meanwhile, are thrash-metal legends, putting out classic albums such as 'Peace Sells ... But Who's Buying?' and 'Rust in Peace,' to name just a couple, over the past 25-plus years. The band will be out in support of its 13th album, 2011's 'TH1RT3EN.'

So, we want to know, if there could only be one headliner on this tour, who should it be -- Rob Zombie or Megadeth? Make your voice heard in the Readers Poll below:
