I'll throw in my 2 cents on Five Finger Death Punch because everyone else seems to be. Their first album is decent. It was faux-tough guy shit, but it wasn't annoying and was some decent groove metal. The second album was alright. A few solid songs, but it had too many mainstream ballads. Their new record is straight-up bad, they are way too full of themselves now and the lyrics are cringe-worthy.
Despite the fact that I'm not really a fan, they do get a lot more shit than they deserve. There are a LOT worse bands out there. These guys do put on a good show and Ivan Moody can sing pretty well.
6/9 Lana Del Rey
6/10 Juicy J
