Less than two months prior, Guetta dropped the Kelly Rowland-assisted “When Love Takes Over,” which is based around a piano melody that’s very reminiscent of Coldplay’s “Clocks.” His other contribution to The E.N.D., the BEP album that contains “I Gotta Feeling,” is “Rock That Body,” a song that’ll sound very familiar to fans of the Justice and MSTRKRFT-style bloghaus genre that was just waning at the time. Most of that’s due to Guetta, who in this era of his career had his ear to the ground, taking existing sounds from the indie, alternative, and dance music universes and optimizing them for mass appeal. A collaboration with French house DJ (and eventual pop-dance mainstay) David Guetta, “I Gotta Feeling” gives off the distinct air of a song you’ve heard before, even upon first listen.
