IMO, Nickelback is the by far the worst band in the history of Roadrunner Records, and that includes nu-metal garbage like Ill Nino. But if you like em, more power to you.
Most albums can be had in Mp3 format for 9 dollars or so from Amazon - support your favorite artists.
Worst band in the history of roadrunner records? Yeah, ok. They continuously pump out hit after hit.
