Amy Winehouse R.I.P. - You Know I'm No Good

"You Know I'm No Good" a song by English recording artist Amy Winehouse, released as the second single from her second studio album, Back to Black. The track follows in the footsteps of Winehouse's previous singles of a mix of jazz and R&B with her soulful, raspy vocals and this time hip hop-inspired beats over it. Recorded solo, and then again with guest vocals from Wu-Tang Clan member Ghostface Killah, the original appeared on Winehouse's album, and the version featuring Ghostface Killah appears on his album, More Fish.

Critical response to the single was positive. For the week of 16 January 2007, the track was chosen as the Single of the Week on the U.S. iTunes Store as a free download. Newsweek also chose the song as its Pick of the Week for 15 January of the same year.Billboard found that the track—"in original form—could be no better", however, it acknowledged that the Ghostface Killah remix added a "ferocious discordant sputter at the midsection." People magazine called the track "instantly memorable."

Prior to this, Winehouse had not seen any success in the U.S., as her debut album Frank was not released there until November 2007. On the Billboard Hot 100, "You Know I'm No Good" debuted at number ninety—one spot ahead of "Rehab", which also debuted on the chart the same week. The single peaked on the UK Singles Chart at number eighteen for the week ending 14 January 2007, in an excellent week for Winehouse that saw Back to Black achieve a new UK peak of number one, previous single "Rehab" return to the UK top twenty, and Frank re-enter the UK chart at number sixty-two more than three years after its first release. To date, the single, which spent a total of eleven consecutive weeks on the UK Singles Chart, has sold 53,272 copies in the UK.
