Yet More Bands

I have been at it again and am not much further with the thing. Can't believe it's taken me this long to pick up on some of the obvious ones, though. I needed to zoom in to figure some out.

Garbage
The Doors
The Police
Phish
Nine Inch Nails
Korn
BeeGees
The Carpenters

More bands...

Okay, upon closer inspection (larger version of the pic), what I thought to be the presidential seal was in fact the back of a half dollar. I am replacing Presidents of the USA with 50 Cent. I also did some creative googling, which is not exactly cheating because I didn't look for any answer lists. Just testing some things I thought might be band names. More possibilities:
Seal
Cowboy Junkies
Stegosaurus
Hole
Madonna
Iron Maiden
Ratt
Big Spoon?
Contortionists
Vines
Crowded House
Mister Yellowman?
