Pink Floyd beat the Doors to become the fourth band to be inducted into the 100% fan-voted Ultimate Classic Rock Hall of Fame.

It seems people are asking the question: why isn't my favorite band up for induction? And Ultimate Classic Rock responds:

"The answer is very easy — more than likely, they are simply not nominated yet. We’re traveling through classic rock history chronologically, based on the year in which the artists released their first studio album."

The Ultimate Classic Rock Hall of Fame was launched in March, and each month eight classic rock artists compete head-to-head to become members of the HOF; no rap artists, no pop artists, just pure classic rock musicians.

And it's all voted on by you, the fans!
