Nothing is cooler than a rock tattoo, and we've collected the best of them. From punk metal to straight-up rock, here are the world's most popular bands and their tattoos. Most popular searches include Aerosmith, Backstreet Boys, and Red Hot Chili Peppers.

The pop R&B singer has sold over 30 million albums worldwide, and won five Grammy Awards. He has several tattoos, including this graffiti-like design of the word USHER being skewered with a sword, like an Usher shishkebob. We call it "The Ushkebob."

The legendary rock band photographed many of their tattoos for the liner notes of their 1991 masterpiece Blood Sugar Sex Magik. And there were a lot of tattoo designs to choose from.

Was there ever a band more tattooed than Motley Crue? Surely the Crue had more IPM (ink per member) than any reigning metal band of the 80's, and possibly any band of all time.

"Chester Bennington" is the name you'd expect from a banker, or an old-time railroad tycoon. Not the lead singer of a wildly popular metal band, whose albums have sold more than 50 million copies. "Chester Bennington" does not seem like a rock star's name, and yet he is, with two Grammy Awards to the band's credit.
