You just have to branch out a bit. Here's a sample of great bands that came out within the last 5 years:
Long Blondes
In This Moment
The 1900's
Riverside
Silversun Pickups
Angtoria
British Sea Power
Fiery Furnaces
It leans a lot to indie pop and chick metal, but that's mostly what I listen to. Your search for new music will be just as fruitful. I recommend turning off the radio and visiting emusic.
Does anyone chart anymore? le sigh.
Chinese Democracy is my favorite album to have come out this year(More than Death Magnetic... But only by a little)
Mastodon and Alterbridge for Rock Band!
Biggest Metallica fan on the forums.
Van Hagar is underrated.
Remember zeppelin1969!
But still, many, but not all, Radiohead fans are pretentious douchebags.
