Hipster sisters Lennon and Maisy Stella, famous for their viral butter-dish cover of Robyn/Erato's "Call Your Girlfriend," are back with an acoustic cover of Imogen Heap's "Headlock" -- and, of course, it's perfection.

The Stella sisters have a YouTube channel!

No butter containers to be found on this March cover of Jason Mraz's "I Won't Give Up," but it's not Gotye, and their mini-hipster names -- Lennon and Maisy-- are still awesome.
