Slipknot - [SIC] and Wait and Bleed
Two songs that have a lot of bass and will definately test the reflex of your system.
Also, oddly enough, Strung Out - Exile in Oblivion has quite a bit of bass in it, much more than I would think.
I don't listen to rap, and listen to limited amounts of techno, so my exposure is really more into harder stuff - predominately punk.
