"I Know There's Gonna Be (Good Times)" is a song by English music producer Jamie xx, with featured vocals from American rapper Young Thug and Jamaican musician Popcaan.

[3] In an interview with The Fader, Jamie Smith stated "I don't feel like I'm very good at making music, in terms of like the technical side of it—it's more like trying stuff out until something that I love happens.

While "messing around" with the track for a little while, he then went to New York City and was listening to Hot 97 driving over a bridge; this experience was described by him as "a real catalyst in terms of what direction [he] wanted to take the song.

"[8] The song was described as a "big, fat, generous morsel of R&B goes to the heart of the way Smith treats his inspirations," with "the subtle Caribbean vibe of so many Jamie xx records", "omnipresent steel drums, exploding with overtones.

[10] Pitchfork Media named the song as the third best track of 2015, adding: "Profane instead of reverent, sun-bright instead of club-dark, drunk instead of ecstatic, "I Know There’s Gonna Be (Good Times)" is about getting low instead of climbing high.

Built from little more than a snare roll, finger snaps, and chimes, Jamie xx made a breezy pop confection that alights on dancehall, trap, as well as doo-wop without ever settling on any one sound.

The official music video for "I Know There's Gonna Be (Good Times)", lasting three minutes and thirty seconds, was uploaded on 28 September 2015 to Jamie xx's Vevo channel on YouTube.
