The BBC have unveiled a rather impressive promotional video to launch BBC Music starring 32 stars of the music world covering the Beach Boys' classic 'God Only Knows'.
The clip sees the likes of Kylie Minogue, Elton John and Stevie Wonder performing the song with a host of lesser-known faces from every corner of the musical landscape.
We managed to name 24 before giving in (we won't tell you who left us scratching our heads, but it's safe to say it wasn't One Direction), but can you do any better?
Anything over 20 and you can officially class yourself as a bit of a musical mastermind, and if you manage to name all 32 then, well, you're a musical genius, quite frankly (or a cheat).
So, if you haven't already, watch the video above (it really is rather good, and you helped pay for it if you own a TV) and then take a long, hard stare at the below pic and see how many you got right as we reveal who's who in the gallery below.
Good luck!
