This was the final track of French rock band Phoenix's fourth studio album, Wolfgang Amadeus Phoenix.
Phoenix vocalist Thomas Mars commented to the Washington DC free newspaper Express: "With the track listing you always know the beginning and the end of every record. We pay attention to the last lyric of the last song because it leaves you with a very strong impression. And this had the most poignant lyrics for a finish. You want to end up with something that ends up with a little weight."
Will.I.am, literally dreamt up "I Gotta Feelin'." Said the Black Eyed Pea: "Have you ever had a dream where there's a melody in your dream? I'll wake up out of my sleep and record that! 'I Gotta Feelin' was one of those songs."
