M.I.A - Kala

Damn. This is a good album.
I'm not a big fan of hip-hop, but the rhythms, samples, and hooks on this album will get stuck in your head after the 3rd or 4th listen.
A couple of gems: Hussel (Feat. Afrikan boy), Mango Pickle Down the River (feat rapping African children).

This album totally redefines how hip-hop can exist. Think Electro-Hop.

Get it.

Pheonix - It's Never Been Like That

This was one of my favorite albums of 2006, and I'm still in love with it. These guys sound like Oasis, Travis, Bloc Party, and Maritime.
The rhythms, melodies, hooks, and choruses these guys throw together make every song sound like it belongs on the radio. This is one of those albums you won't be able to get out of your head for days.
Amazing. Get.
