I just found this site and was surprised I couldn't find it on here. I haven't heard of many of these guys but the site compiles, or shall I say exposes, nudes of men in: emo, hardcore, screamo, pop, and rock band members. They also have nudes of women who have slept with many of the guys, and random people with tattoos.
Main site with all men, women, and band members
