48. Alexandra Burke, Hallelujah (2008)

Oh shush yourselves, indie boys. I love Leonard Cohen's sleazy original from the bottom of my heart, but there's no denying that Hallelujah is also, at its core, a truly fabulous love song, and I'm delighted that more people will get to know it now. Alexandra's not got a bad set of pipes either – and her last verse is truly lovely.
