Unless your head was under a rock, you know that "Change" was the big theme of 2008. So why was popular music so rooted in the past?
Rock had a big resurgence, with the unexpected release of Guns N' Roses' 13-years-in-the-making "Chinese Democracy," the blockbuster success of AC/DC's Wal-Mart exclusive "Black Ice," the return to thrashing guitar heroics of Metallica's "Death Magnetic," Bon Jovi staging the year's biggest concert tour and Kid Rock enjoying his biggest year ever. Old bands ruled again via video games "Guitar Hero" and "Rock Band." This year's "American Idol" was even a rocker dude, David Cook.
Of course, Barack Obama was the changemaster in 2008 and a lot of big names -- from Bruce Springsteen and Bob Dylan to Jay-Z and Dave Matthews -- threw him their support. But only a few, including John Mellencamp, TV on the Radio and Will.i.am of Black Eyed Peas, made music to address the times that are a-changing.
Britney Spears continued to make headlines more for her personal life than her music. The same could be said of her role model, Madonna.
If you wanted musical change, there was Kanye West, the rap megalomaniac who became an R&B singer this year with an assist from the computer program Auto-Tune. Another rapper who mixed hip-hop with Auto-Tune singing, Lil Wayne, created the year's biggest-selling album, "Tha Carter III."
New faces from the Old World
After Amy Winehouse's Grammy-grabbing success in 2007, we looked again to England for new female pop voices as a quartet of young thrushes -- Leona Lewis, Duffy, Estelle and Adele -- made big splashes in the States.
The most prominent U.S. newcomer, Katy Perry, stepped into the spotlight with "I Kissed a Girl," an open-minded experiment that captured the imagination of pop fans while her fellow Californians voted down gay marriage.
