Yea it's a classic :)

but never liked listening to that song, I was like "whoa no way!" at first but it's incredibly corny lol

I prefer listening to Nu Metal, Hardcore-Punk and sometimes Punk-Rock, while playing DotA :)

If you can work with those genres try:

Sick of it all - Faithless
Comeback Kid - Wake the dead
Papa roach - blood brothers
Linkin park - a place for my head
Celldweller - switchback
sum 41 - open your eyes
Embraced by hatred - down to concrete
a day to remember - fast forward to 2012
Stick to your guns - enough is enough

i am genraly a Punk Rock/ alternate Rock fan myself but i have found Rise Against to be a very good dota 2 back track

some suggestions are:
Rise agains: Satellite
Offspring: your going to go far kid
Authority Zero: A day to remember
Rise Against: Bricks

and the always classic
Flight of the Concords: To many ****s on the Dance floor

just a few suggestions

Just some techno/dubstep off the top of my head:

Pendulum (Australian band, btw :D)
Skrillex (Meh..)
Arion
Bassnectar - Lights remix
