Beyonce - Halo
Written and produced by OneRepublic's Ryan Tedder, the man behind 'Bleeding Love', Beyonce will be hoping she can emulate it's huge success with this track.
It has been reported that Leona Lewis was originally earmarked to perform the song but it was eventually handed to Beyonce, a decision that Mrs Jay-Z will no doubt be delighted with, considering its success.
As well as a strong chart performance, Halo won 'Best Song' at the 2009 MTV Europe Music Awards , and 'Best Female Pop Vocal Performance' at the 52nd Grammy Awards.
The video features actor Michael Ealy as Knowles' love interest and was directed by Philip Andelman.
