The Nick Jonas of 2014 is practically unrecognizable from the onetime leader of the Jonas Brothers. Forget all the shirtlessness and the ab workouts and Marky Mark homages. The music of "Nick Jonas" (Universal) bears no resemblance to his previous work, as he chases trap music via Katy Perry ("Numb"), "Faith"-era George Michael ("Teacher") and modern-day Bieber ("Want You"). He seems especially interested in claiming the Biebs' corner of hip-hop and dance pop, a lucrative, teen-friendly market that's currently leaderless with Bieber in a timeout.
