Both artists co-wrote the song with Jacob Luttrell, R3hab, Fabian Lenssen, Yoan Chirescu, Raphaël Judrin, and Pierre-Antoine Melki.

"Finally Found You" is a dance-pop, electro house song about a guy finding the love of his life at a club and declaring to never let her go.

[4] In August, Enrique premiered "Finally Found You", with the single being available to download from the US iTunes store on 25 September,[5] while in the UK it was released on 10 December.

"[7] An alternative version, featuring Puerto Rican reggaeton rapper and singer Daddy Yankee, was recorded for the Latin market.

[9] "Finally Found You" features a rap from Cambridge rapper Sammy Adams and is a dance-pop and electro house song,[9] with sparkling synths.

[10] According to PopCrush's Scott Shetler, sonically, the song features exactly the same dance-pop vibe of the singer's recent hits like ‘I Like It’ (2010) and ‘Dirty Dancer’ (2011).

[11] Lyrically, "Finally Found You" sees Iglesias finding the love of his life at a club and declaring to never her let go, asking his "object of affection to ignore the advice of her friends and to stick with him till the end".

Robbie Daw of Idolator was aware that the song "finds him sticking to the tried-and-true dance-pop formula that has kept him in the upper reaches of the charts since he first crossed over to pop stardom 13 years ago."

However, Daw positively said, "who doesn’t love a guy who whispers sweet nothings and can give you a good beat to dance to at the same time?.

Shetler also saw that Adams verses "don't necessarily fit the theme of the song, but chances are listeners will be so busy dancing they won’t notice the inconsistency.

"[12] Kim Alessi of Commonsensemedia wrote that "There's really nothing original about "Finally Found You," but the song does match Iglesias' sexy Latin dance-pop style and heartthrob persona, and is reminiscent of his other recent hit dance singles featuring rappers.
