Black Eyed Peas' Elephunk. Of course, it was stolen out of my car along with my Alpine H/U, amp, subs, pillows(and pillow cases... I had just bought them at Bed Bath & Beyond), 40 DVDs, and quarters(motherfvckers cleaned out the change pocket too!)
I really liked the CD. I bought it having heard only "Let's get it started", but the rest of the CD was pretty good too.
