I only really bothered with Kate Nash's, which I'm really mixed on, some songs are brilliant, but others (Mansion Song = wtf!) are just terrible.
I've not heard Kele's, I like Tenderoni, but I miss Bloc Party
I've also not heard MGMT, but they do my ****ing head in, I love Time to Pretend and Kids, if they're not happy with being in the industry then they should stop making music, that simple really!
