Listen To This: Coastin' On Mathematics

I came really close to not posting anything today before finding this sick mashup of Mos Def's "Mathematics" and Zion I's "Coastin'".  These are both two fantastic songs, and the piano riff complements Mos Def's vocals very well.  I would also recommend checking out the original versions of both songs, as the original Premo beat on "Mathematics" is crazy and "Coastin'" is a nice chill song. EDIT- I actually don't really like this song...
