When good bands go bad. These are the bands who have a solid discography overall, but just couldn't resist putting out that one awful music video single that the peasants would love. View with caution.

10. Cryptopsy - "Worship Your Demons"



The most recent sell-out. Cryptopsy changed their sound to appeal to the current Hot Topic metal audience.

9. Sepultura - "Roots Bloody Roots"



Sepultura saw dollar signs in rap-metal and never looked back.

8. Celtic Frost - "Cherry Orchard"



I guess black metal doesn't pay the bills like glam. Celtic Frost would like you to forget this one.

7. Helloween - "When the Sinner"



A black eye on an otherwise pretty solid resumé.

6. Judas Priest - "Johnny B. Goode"



What a dreadful choice for a song to cover. The chorus makes me want to kill.

5. Anthrax - "Nothing"



Alternative-thrax. Why did they do this to us? We were so good to them.

4. Black Sabbath - "It's Alright"



I'm not sure if this qualifies as a sell-out, since I don't think ANYONE actually liked this song.

3. Kiss - "Made for Loving You"



Whether Kiss were ever actually metal or not, this little disco number certainly doesn't help their case.

2. Megadeth - "Breadline"



It sounds like a theme for a bad '90s TV show. Where are the shreds Dave?

1. Metallica - "Until It Sleeps"



THE ULTIMATE SELL-OUT VIDEO!!!
