Not bad. I like Vegas. I like how he's rapping fast, cuz it's kind of like the Beastie Boys. It's just fun to listen to. Not every song he makes has to be serious, but it has to sound good. And his new style is a work in progress. His next album should have a lot of songs where he raps fast. I think this all started with Rap God. He's developing a new style, but at least it is a unique style. I would like some better hooks though, but oh well.
I think I'd rather have Eminem rap fast then to make songs with Rihanna and Bruno Mars. His style is a work in progress. He was experimenting with Relapse. That failed. Then he experimented with Recovery and tried to go pop. Then he experimented with MMLP 2 and tried to make it about nostalgia. It looks like his next album will be a really fast paced flow. If it works, you got to hand it to him for making all his albums different from one another. I think that's where he's going. Berzerk & Rap God style.
