Stephen Albanese

fun.'s "We Are Young" and Gotye's "Somebody That I Used to Know" have been battling it out to be the No. 1 song in America for what feels like months now, with both songs taking turns at the top spot, and now fun. has gotten together with Hayley Williams of Paramore to cover their chart rival's track!

fun. recorded the song during BBC Radio 1's Live Lounge session in the UK, with Williams dropping in her vocals all the way from Los Angeles. The result is, as you might have predicted, fantastic. Listen to the song below and let us know what you think of the cover in the comments!
