Selena Gomez [1] is back and better than ever (not that you had any doubts). After entering rehab and spending time out of the spotlight [2] for a few months, the pop star recently returned with a ridiculously catchy single, "It Ain't Me," [3] that had fans champing at the bit for more new music. Thankfully Gomez has just gifted us with another track: a cover of Yazoo's 1982 hit "Only You" for the 13 Reasons Why [4] soundtrack. She serves as executive producer [5] on the Netflix drama — which follows high school student Clay, who receives a series of cassette tapes recorded by Hannah, a classmate who recently committed suicide — and said on Twitter [6] that the song was "inspired by Hannah and Clay's story." It's haunting, beautiful, and quite possibly her most emotional song yet.
