Broaden my musical taste, dear ones!

Hello /music/, I'm getting weary of not having anything to listen to. I need some good bands and I don't know where to start. I'd try Pandora but a majority of the time I don't find it to be satisfactory. The Arcade Fire - Power Out and The Knife - We Share Our Mother's Health are two of the best songs I've ever heard. If someone could suggest some bands, that'd be nice.

Arcade Fire is a band of nerds thinking that adding weird instruments to their music makes it good.
