Thankfully, the busy workload hasn't affected her quality control. Penned by OneRepublic's Ryan Tedder and originally offered to Leona Lewis, 'Halo' is a contemporary power ballad in the 'Bleeding Love' mould: modish beats, a simple piano melody and loads of emotion. "Everywhere I'm looking now, I'm surrounded by your embrace, baby I can see your halo, you know you're my saving grace," Beyoncé sings over Tedder's bombastic production. Could Lewis have pulled this off better? Well, that's a matter of opinion of course, but Mrs. Jay-Z doesn't leave much room for improvement.
