The track received positive reviews from fans and critics alike with most praising the band's polished new sound, owed partly to U.S. album producer, Matt Wallace (Maroon 5).

Mousetrap Heart received heavy airplay in Australia soon after its release to radio in May 2010.

The female singer featured in Mousetrap Heart is Carmen Smith.

The single kicked off the Mousetrap Heart Australian Tour, in support the single and album.

The music video was shot in Los Angeles and features LA-based, Argentinian dancer Carolina Cerisola dancing around and on a piano that singer Rai is playing.
