The Greatest Collaborations of 2011

There are two ways to sum up 2011 in music, that would be collaborations and reunions, both of which are double edge swords in their own right.

A collaboration can be bloody painful or elatedly sublime, here we're going to pay tribute to the best collaborations this year had to offer.

We've interspersed some of the tracks with some artists that may have flown under the radar but nevertheless are more than valid.

We've got Rihanna and Kanye dominating alongside guest features from Dizzee Rascal all the way to Tony Bennett. Watch out for our list of the weirdest collaborations of all time next week if you fancy a chuckle.
