Enrique Iglesias Feat. Nicole Scherzinger

The collaboration appeared on Iglesias’s Euphoria album in 2010, a record that moved between Spanish and English material and several different kinds of pop partnership. Produced by Mark Taylor, “Heartbeat” belongs to its more restrained electronic side rather than its most extroverted party records.

The production uses a steady pulse and repeated melodic shapes to hold the two voices in one setting. The emotional movement comes from the exchange: a line is offered, answered and then heard again with a different weight because the other singer has entered the conversation.

The original album version is the clearest introduction. It leaves enough room for the contrasting tones to remain audible, with the arrangement widening around the chorus instead of covering the vocal details.

The duet is effective because it does not need to resolve every difference between the singers. Each performance keeps a recognisable character, and the song gains tension from that small distance. Heard among the brighter Euphoria singles, “Heartbeat” offers another view of the album’s collaborative idea: a pop production can become more intimate when it gives two distinct voices something specific to answer.
