If you listen to modern-rock radio, then you've heard Nickelback. This Canadian quartet's second album, Silver Side Up, sounds powered by Fuel, motivated by Creed and stained by, uh, Staind. Nearly every song seems trapped in the amber of early-Nineties Seattle aesthetics, the sonic equivalent of too many unfortunate goatees. It's all here: loud-soft dynamics, a lighter-waving power ballad, aggro lyrics that touch on all the expected trauma topics (abuse, depression, golddiggin' women) and those slightly discordant yet catchy chord progressions. The band delivers its sound professionally, but if you're looking for originality, you might want a full refund instead of a Nickelback.

“My President”

Young Jeezy teams up with Nas on this track, in which he compare his own success with the idea of an African-American winning the Democratic Party's nomination in the 2008 presidential election. "When I pulled up in my car, that s--- was unbelievable to people in my neighborhood because they were like, 'We grew up with him. How the hell did he accomplish this?'" he told Rolling Stone. "I feel like it was the same way with Obama. I grew up all this time, but I've never seen a black man this close to running this country."
