What are your top 10 hip hop songs of the year?

So, my online radio station used to play lots of good songs and occasionally would play good hip hop/rap songs I had never heard before. Now, it seems they don't play anything new and (as most of you know) the radio plays a lot of crap and the good stuff is overplayed (especially where I live). Can you give me your top ten (or even just 2-3) songs of the year? Not stuff that is already overplayed on the radio (like Boom Boom Pow) but stuff that I may not have really heard yet. thanks...
