I have such a wide variety that it's ridiculous. Generally when I'm boarding I have a playlist on that has Matisyahu, Motion City Soundtrack, The First Descent soundtrack, Juno Reactor, System of a down, Incubus, Pietasters, Hold For Swank (local band). generally the things with a good solid groove.
