• Karmin were a pop-rap duo made up of Amy Heidemann and Nick Noonan, who met at the Berklee College of Music. Their name derives from the Latin word "carmen," meaning "song," with a slightly altered spelling to "hint at karma."
  
  The pair first gained recognition from their covers of popular hip-hop and pop songs posted on YouTube. These included their unique renditions of Chris Brown's "Look At Me Now," Nicki Minaj's "Super Bass," and LMFAO's "Party Rock Anthem." They built a huge following on the platform and attracted interest from record companies. They signed with Epic Records in June 2011; their first single, "Crash Your Party," was released in October of that year, with their debut EP Hello arriving in May 2012.
  
  Karmin released the full-length album Pulses on Epic in 2014, but then left the label and released the album Leo Rising independently in 2016. The following year, they rebranded as Qveen Herby, with Amy the focal point.
• This cheery pop track had all the makings of a hit, and it delivered, landing Karmin on the pop charts with an original song. Lyrically, it finds Amy Heidemann begging a guy not to leave her brokenhearted tonight. The song incorporates her trademark rapping in the verses, with a big, hooky chorus that she sings.
  
  The pair collaborated on the track with fellow Berklee alum Claude Kelly (Kelly Clarkson's "My Life Would Suck Without You," Jessie J's Price Tag") and John Hill (Shakira's "She Wolf, Christina Aguilera's Bionic). It was produced by dance-pop hitmaker Benny Blanco, whose resumé includes Katy Perry's "I Kissed a Girl," Kesha's "TiK ToK" and Bruno Mars' "Grenade."
• In the video, Amy Heidemann sings this to Nick Noonan as if she's aflutter in love with him. It wasn't a stretch: They were engaged at the time and finally got married in 2016.
• The song was released on February 7, 2012. Four days later, the duo performed it on Saturday Night Live backed by a full group. Heidemann sung-rapped her vocals dressed in 1940's South Pacific-esque attire.
• The song's music video was filmed on location in Los Angeles and was choreographed by Richard Jackson, who is best known for working with Lady Gaga. The clip is loosely based on how the pair met, and is set in Heidemann's apartment, as she thinks back to the previous night when she met Noonan for the first time.
