A few months after this song was released, the duo Karmin posted a cover on YouTube
that launched their career. In the video, Karmin's vocalist, Amy Heidemann, does all the raps, keeping pace admirably on Busta's section. She also cleaned it up, taking out the curse words and substituting "on my crack" for Chris Brown's "on my d--k." Amy used cue cards when she made the video, but had to memorize the lyrics soon after when they performed it on Ellen
and a few other talk shows.
A wholesome couple with pop sensibility and a female vocalist who can fire off rapid rhymes, Karmin got the attention of the major labels and fielded offers. They went with Epic and did well, scoring hits with "Brokenhearted
" and "Acapella
." But after four years on the label, they wanted more control and a break from the relentless pace, so they left Epic and became independent. In 2017, they retired Karmin and Amy emerged as Qveen Herby
, a rapper with attitude. Her first release was "Busta Rhymes
," a tribute to the rapper and showcase for Herby's speed rapping skills.
