Song of the week 8

And it's the 8th week already,not counting the 2 that I was missing.Oh let's cut to the chase,shall we?
This week I shall be listening to one of the best collaborations this year (since there hasn't been any) and it's not even cheesy.Some people might have expected some more since it's Coldplay and Kylie Minogue,but some people just don't enjoy chill-out (not that it's chill-out,it's just chilling...).Okay I'll shut it.What does "Lhuna" mean (besides possibly "Moon")?
