To the OP, if you want to bump something electronic that is not rap, I would suggest that you look into some Drum and Bass. Pendulum's first CD Hold Your Color is pretty badazz and will let you feel your subs without rap. I recommend the track Tarantula by them! To all the rap worshipers, I have to say sorry, but I would rather be involved in another head on collision than be tortured with listening to Rap (which in my opinion is shorthand for Crap).
Don't get me wrong, I like Rock, Metal, and Tool (lol)... I just wanted to let you know that there are alternate electronic forms of music that are not rap that will send your subs into orbit and get you strange looks!
Lastly, although I didn't read through the whole thread, I would recommend some Chimaira for metal with a little bit of Thump!
OK, I will go into hiding now for the Drum and Bass suggestion. At least I didn't recommend Electro-house and breakbeat.
