Best music of 2011

Well, a pinch and a punch and all that. Given the time, I thought I would start a thread inviting people to add their list or opinion. In my view:
a) it can be albums or songs
b) they can be released this year or many years ago, just your favourites for 2011.
c) you don't need a magic number of 10. It can 8, 17, 2, whatever

I will start by saying my favourite Stereolab release was Aluminium Tunes
