Julio Bashmore's 1st one was big for me, but more on a personal level. Some of his big tracks in 2011 were really seminal in pushing me more into House (really was into Nu Disco / French Touch stuff before), and his mix had a pretty wide array of things both old and new.
Also, really digging the new Floating Points mix - http://www.bbc.co.uk/programmes/b06ppn0p
He's one of the best I've seen live, so personal/sentimental reasons for this one too I suppose.
