Umbrella.

I didn't like Rihanna's song Umbrella at first but I have grown to love it. I did my research about the song and learned that it's one of the most covered songs of 2007.

Biffy Clyro and John West sing acoustic versions.

Mandy Moore and Marie Digby give it a more feminine pop-ish touch.

McFLY, Plain White Ts, Vanilla Sky (a pop band from Rome), and All Time Low (which was included in the Pop Goes Crunk album) made Alternative Punk versions.

Chris Brown and Rihanna did a remix and changed the title to Cinderella Under My Umbrella.
