Yesterday we got the official release of an older track a lot folks have already heard: Drake's 'You Know, You Know,' which was recorded in 2009 with Kanye West producing.

Today it's a song from another dynamic duo that you may have already heard, but never in such high quality.

Check out the "official" version of the 2006 Lil Wayne & Juelz Santana track '1 Arm', which the song's producer Streetrunner just put on his Soundcloud page.

Remember when Weezy ran the show, and Juelz looked poised to be the next Wayne?
