Amy Winehouse - Take the Box (2004)

Co-written and produced by Amy Winehouse and Luke Smith (Keyboardist/Producer) for her debut album in 2003, Frank. Released as the album's second single on 12 January 2004, it was the highest-charting single from that album, peaking at no. 57 on the UK Singles Chart. The line "Frank's in there and I don't care", refers to her dog of that time of the same name. The album was also named after him.
The single for Take the Box features an exclusive B-side, titled Round Midnight. The song's content covers Winehouse as she leaves her lover after discovering he is having an affair. The song details her acceptance of the fact that its over as she tells the lover to literally "take the box" of stuff he left.
Frank is an overlooked gem and I couldn't stop playing this at the time; I had a feeling she was heading for bigger things, but with a sound aimed at the Katie Melua audience. Rehab changed all of that, and her, forever.
