Katy Perry was so serious about music that she obtained a GED in her freshman year of high school so she could chase her dream. In 2008, the world heard her debut album One of the Boys, and they liked it. Now she's back on a release that features the chart-topping single California Gurls.

Muse returns with the follow-up to their U.K. chart topper Absolution. Black Holes and Revelations features influences from current events, which are reflected on the singles Supermassive Black Hole and Knights of Cydonia.

"There must be a healthy middle when it comes to capturing the essence of Brit-pop. Something in between the impenetrable swagger of Liam and Noel Gallagher and the vacuous and hollow bravado of Jet that can both pay homage to big riffs and bad attitude, yet still maintain a unique personality, which is what made the rock gods of yesteryear so endearing." --
