Album Quiz 2

I've decided to release these once a month until I get bored. BEHOLD

http://picasaweb.google.com/philgdawson/AlbumQuiz2#

There are 50 albums so write your guesses in the comment field on each pic and as I see the correct answers I'll flag the album as done. As with the last quiz, please verify your response is secure by clicking back and forward after you enter one. I've tried to make some simple, some odd, some brain twisters, some alternative and some so mainstream-commercial its scary.

Hints:
1. None of the albums are Best Of's, Greatest Hits, Live, Compilations or anything other than an official release.
2. The same artist may feature more than once.
3. You can use the net as much as you want so everyone has the same UNfair advantage!

I think this one is a little harder than the last but as it showed, its not the hardest that remain unsolved.....

Enjoy!

UPDATE
13.15: Wal and Smads have had a crack .... Anne takes to the floor! - 16 down : 34 to go. The guys here in the office got 9 more within 5 mins...... cmon, LIFT!
15.30: The wall has hit early. Radio silence until Smads gets home and tells Bel there's another Quiz! Get your answers in while you can....

7/12 8.30: Kathy takes a print out to a gathering of her entourage and picks up 13 over the weekend. I've got inside knowledge that a few sneaky google searches revealed a couple of answers so don't give up just cos you don't have the album! (eg: #40 has a circle thing so google 'album cover circle'. Creed appears as the third link.......lucky the album's called Full Circle i spose!) 22 to go.
9.30: Kathy picks 3 more as she noses to the finish.... absolutely dominating Quiz 2
13:00: ....and Ditto on 2 more. 17 remain!
15:30: All quiet on the frontline - Clues will go up at 12 tomorrow.

8/12 16:00: CLUES ADDED!

9/12 10:30: Wal has overnight success and Adam sweeps the 4 - 9 to go!!!
11:45: Adam takes 2 more - 7 remain.
