- Songfacts: A Song For You by Amy Winehouse
Donny Hathaway was Winehouse's all-time favorite artist and during the spring of 2009 she recorded her own interpretation of Hathaway's version (of A Song For You) in one take, at a studio that she had built at home in her attic. Winehouse laid down the track in the midst of her struggles with drugs and alcohol and the recording ended up as the closing track of her first posthumous album, Lioness: Hidden Treasures. "She said to me, we can make the new album here," the song's producer Salaam Remi recalled during a listening session. "We don't have to worry about the paparazzi. She was just lying down on a couch, with the mic in her hand and by about halfway through the song she was crying, really weeping, with makeup running down her face." Remi took this bare recording of just Winehouse and guitar and added further production to it. 
After this song finishes playing, we hear a snippet of Winehouse talking to Remi, discussing her hero. "Donny Hathaway," we hear her say. "It was like he couldn't contain himself … he had something in him, you know."
