OK, these 3 probably won't be the best, but they certainly are three albums I can listen to over and over again.
Amon Tobin - Splinter Cell-Chaos Theory Soundtrack

I think the game becomes good Through this soundtrack, but the soundtrack itself is just awesome. I don't think there's much more out there that can carry feelings like this album.
Yeah Yeah Yeahs - Fever To Tell

An awesome mixture of Rock, Pop, Experimental and I don't know what else. The singer's voice is outstanding and the beats are fresh. Sadly enough, the two newer albums aren't even remotely close to this one.
Kings Of Convenience - Riot on an empty Street

Now this is pure pop music. Whenever I want to relax propery, this is the perfect album for it. They really live up to their name. Some of you may have heard of Erlend Oye (my keyboard doesn't know the proper characters for the name), this was one of his projects. Feist does the vocals on a few songs.
