It's our weekly hotly contested Backs v Forwards knowledge/trivia contest. This week we have Konrad Hurrell v Eddy Pettybourne.

The questions were:

1. Which female artist has sold the most records/songs world wide?

2. Which was the most popular song of 2015?

3. Finish the lyric of this well known (Beyonce) song ... 

Watch Konny add some style (and vocals) to his answers.
