I want one.

I've more or less switched from pandora.com to deezer.com for what music I listen to when I'm playing WoW or doing other stuff that would let me sit at the computer listening to music for hours. The only problem with Deezer vs Pandora is that Pandora will give me things to listen to without me having to tell it exactly what I want to hear all the time. Deezer has a suggestive playlist too, but in my experience it sucks. So, at Deezer I always just play & randomize my playlist. That's why I switched, I can hear exactly the songs I want to hear whenever I want.
Here's my dilemma: I need some more music suggestions.
My playlist currently consists of:
Eminem & D12 discographies, some DMX, most of 50 Cent's stuff,
Dethklok, Devildriver, all the Mindless Self Indulgence they had,
Freestylers, Hollywood Undead, Darude, Prodigy, Rammstein, Pendulum,
covers of a couple Debbie Deb songs, Sabaton, some Ludacris,
HIM, Rammstein, Riot by Three Days Grace, No Jesus Christ by Seether,
911s a joke by Public Enemy, Mr. Brownstone by Guns n Roses.

What else should I have? I wish I had more decent techno on there.
It's starting to get swamped with death metal since I added a ton of Devildriver, which is why I didn't add Sepultura, Amon Amarth, etc.
I can add specific songs, which is handy, but not when I draw a blank on songs I really like.
So, I'm looking for more stuff that's like what I already have... only different.
I'm looking for high energy stuff or stuff with a catchy beat, please let me know your recommendations.
