I think the Beast is still the best chance at a mainstream single. Come Gangsta is the best song off the album that I've heard so far. Unfortunately, the sampler only has the first verse which is the weakest of the three.
Riot maker sounds like it's gonna kick ass - everything kid rock wishes he was. I think they might have been trying a little to hard with bout to bubble. It's a solid song, but doesn't really tell you what tech is about. The hook is not nearly as catchy as some of the others (beast, jellysickle,mwmbmg for instance).
All in all, this is going to be a great album. Good luck.
