Written by Amy Heidemann, Nick Noonan, Claude Kelly, Benny Blanco, Emily Wright, Henry Walter, John Hill and Richard Head, produced by Blanco, Cirkut, and Wright, and recorded in the late summer of 2011, the single leaked on January 27, prompting the duo to upload it to their YouTube account on January 30, and was made available for digital download on February 2, officially being released to radio on February 7.

[7] "Brokenhearted" was well received from critics who complimented Heidemann's vocal prowess and the production's energetic vibe.

"[8] Grady Smith of Entertainment Weekly calls it a "sunny pop track... which features another dose of Amy’s trademark rapping over a Dr. Luke-esque beat.

"[2] Andrew Unterberger from Popdust says, "Last year’s "Crash Your Party" was a good start, but "Broken Hearted" faces a much better chance of breaking them through to the Top 40, with a Katy Perry/Dr.

Luke style super-pop groove, the first few notes are all but guaranteed to give you "Last Friday Night" flashbacks and a chorus sentiment ("Don't you leave me brokenhearted tonight") that has definite lovelorn-party-anthem potential.

"[9] MTV's Liz Barker says it may be "the sunniest song to ever bear a title like 'Broken Hearted,'" with a "super-slick flow that Amy shows off.

She sits down on her bed and trades her discomforting heels for the comfort of throw rugs under her bare feet, grabbing hold of her mic stand and flashing her band a reassuring gesture.

The night before, Amy, Nick, their band members and other friends party in an apartment, complete with drinking, dancing, a game of darts and table tennis.

[2][8][16] The band continued a promotional push for the single by appearing and performing the song on VH1 Big Morning Buzz Live, and also announcing that the release date for the album was set for May 8, 2012.
