Justin Timberlake was busy Sunday night.
Early in the evening, the singer made his highly anticipated return to the Grammy Awards stage -- his first performance there since 2009, when he and Al Green filled in for Chris Brown and Rihanna -- with a lavish, sepia-toned performance of two tracks from his upcoming "The 20/20 Experience," due out March 19.
But for a pop superstar slowly making his way back into music, that still wasn't enough to satisfy the ever-ravenous buzz machine. So early Monday, Timberlake posted a fourth "20/20" cut, "Mirrors," online -- and at eight minutes long, it's basically the equivalent of two of his typical songs.
Listen to "Mirrors" -- which to Pop & Hiss' Grammy-fried ears suggests like a cross between Timberlake's "Cry Me a River" and "November Rain" by Guns N' Roses -- below.
