Even if you own only one Pearl Jam album chances are that its the band's 1991 debut album "Ten." That album has just reached the 10 million mark in US sales, making it certified Diamond.

"I'm happily shocked to hear that. Wow," Pearl Jam guitarist Mike McCready said, "We had no idea that it was going to ever do that well. I just felt like it was a really cool record and that I was in a good band."
