Thanos.
Well i fell that he likes rock/metal on the outside for show, Metallica, Deftones, stuff like that. But what he realy likes is classical music. Wich he listens to when no when is around lol.
Just the feeling i get from his persona.
As cliche as it sounds, I can easily picture Gambit in some sort of scene right out of Water Boy, riding on one of those swamp hover crafts, with Creedance Clearwater Revival in the background.
Thanos, Magneto and Galactus always strike me as people who would listen to Opera or Orchestral.
Dr.Doom probably more European Orchestral and The Darkness.
Banner would probably listen to something passive just to keep his anger down but Hulk, if he did have a preference, would likely choose Heavy Metal or Hard Rock. I think something along the lines of Metallica or Deftones.
Spider-Man seems like a bit of Smoother Rock. Like Incubus.
The Silver Surfer would probably like something like....Radiohead.
Wolverine would be Rage Against The Machine I think.
Punisher always strikes me as a Slayer sort of guy.
I think Psylocke would like Muse. Specifically the songs "New Born" and "Bliss".
-AC
Punisher is all about the Megadeth, they even made a couple songs about it. Dave Mustaine rocks so hard it almost hurts me to listen. That's how badass Megadeth is.
Magneto and Dr Doom , would definetly listen to Rachmaninov, it makes all the sense.
Silver surfer the cover from joe satriani, pretty cool the name of the album is surfing with the alien i think, and did you guys seen reservoir dogs, in the movie a poster of him appears in the house of tim roth.
Surfer listens - Radiohead and Sigur Rós, but he also needs to listen something more heavy sometimes when he is more angry, something like nine inch nails, or At the drive in, or rage against the machine.
spider man - peter is a guy that must listen to alot of music, massive attack, tricky, radiohead, dEUS, smashing pumpkins, muse, placebo, etc etc
wolverine - Led Zeppelin, Black Sabath, Dire Straits, Doors, Guns n Roses and Metallica ( he has 100th years he has to know alot of things)
Batman: well bat has to listen to some dark or mystic music, i would say he listens to Tool and Dead Can Dance. And maybe alice in chains. He should listen trip-hop as well, like massive attack, tricky, and portishead.
Cyclops doesn´t listen to justin come on, he is probably a great queen fan.
iron man i am imagining him listening to Iggy pop, look for example lust for life.
