I think smoking crack tops this list. Not really...well...it all depends on who you ask.
Coheed and Cambria (duh), Opeth, Dragonforce, Deltron 3030, Wu-Tang Clan, blah, blah, fucking blah...
Buckaroo Banzai, Big Trouble in Little China, anything by Argento, Fulci, shit..anything gory and fucked up. If you want to lose your lunch check out the August Underground series, or even better try the Guinea Pig series.
BSG, Dexter, Masters of Horror, and just about anything other than reality tv.
Song of Ice and Fire series by George R. R. Martin, Damned near anything by Chucky P., I would go for something of significance here, but I really just like pulp bullshit books, If I want something to make me think I'll just turn on my fucking brain.
