6. Mesfin Fekadu's pick...Justin Timberlake
“The 20/20 Experience -- 1 of 2”: Mr. SexyBack is also Mr. ComeBack. Justin Timberlake returned to music after seven years with a 10-track album that didn’t follow trends in pop, but still became 2013’s most successful album. Along with Timbaland, the prince of pop has mastered the falsetto and maintains a smooth, mid-tempo sound throughout the 70-minute adventure. The songs feature the traditional Timberlake transition—how could you not adore “Strawberry Bubblegum”—and these are tunes that only he could sing. Listening to the album’s sequel, released months after, lets us know Timberlake isn’t superhuman. He makes mistakes, too.
