Oh my ears!

If you thought that Bing Crosby & David Bowie's Yuletide duet on "Little Drummer Boy" was the nadir of music, you will be shocked to hear that anoher duet version of the same song has upped the ante.

Justin Bieber Featuring Busta Rhymes have managed to produce a track that makes Bing & Bowie's version seem almost listenable.

I did say 'almost'.
