Christina Aguilera

Like every other early-aughts pop starlet, Christina Aguilera has struggled to find her place in the modern pop landscape, trying her hand at acting and becoming a vocal coach on the TV series The Voice. Aguilera's powerful, versatile voice has always been her biggest asset, so it's no surprise that the singing on her new album, Liberation, is amazing, even when her song and production choices falter. If you can look past ill-conceived forays into trap and R&B (including the lackluster Kanye West-produced single “Accelerate”), you can look forward to hearing some unabashed pop anthems alongside classics like “Genie in a Bottle” and “Beautiful.”
