"Good Feeling" is a song by American rapper Flo Rida from his 2012 EP of the same name, also appearing on his fourth studio album, Wild Ones. It was released as the album's lead single on August 29, 2011, in the United States. The song was written by Flo Rida, Dr. Luke, Cirkut, Breyan Isaac, Arash Pournouri, Avicii, Etta James, Leroy Kirkland and Pearl Woods. It was also produced by Dr. Luke and Cirkut.
The song contains vocal samples from Etta James's 1962 single "Something's Got a Hold on Me", which is why James, Leroy Kirkland and Pearl Woods received writing credits. Avicii and Arash Pournouri received credits as well because Avicii's song "Levels", which also sampled the Etta James song, is used as the primary musical interpolation throughout "Good Feeling". In addition, this is Flo Rida's fourth collaboration with Dr. Luke (after "Right Round", "Touch Me" and "Who Dat Girl") and second collaboration with Cirkut (after "Who Dat Girl"). The three would next collaborate with Taio Cruz on the song "Hangover". "Good Feeling" peaked at number 3 on the Billboard Hot 100, becoming Flo Rida's sixth top-ten and fourth top-five single on the chart. The song became a top ten hit in 16 countries.
