YouTube sensations Karmin are once again giving a hip-hop song their own friendly pop treatment. This time, it's the Cory Gunz-assisted Lil Wayne track '6 Foot 7 Foot.'

As they did on their version of Chris Brown's 'Look At Me Now,' Karmin turn the rap track into a fun piano number. Amy Heidemann provides a humorous element with her flawless flow. With a huge smile on her face, she raps, "Young Money militia, and I am the commissioner / You don't want start Weezy, cause the F is for finisher."

Not to be overlooked, Nick Noonan provides the harmonies and backing vocals that on Weezy's version come from a sample of the '50s hit 'Day-O (The Banana Boat Song).'

Though Karmin are building up a following (19,000 Twitter fans and counting) thanks to novelty versions of rap songs, they can also legitimately sing, as evidenced by their other videos, which include covers of Adele's 'Someone Like You' and Cee Lo Green's 'Forget You.'
