I didn't know there were actually different versions of the 30 Day Song Challenge, and I was doing the dull one. So let me do the 2nd one again. :D
2/30 Your favorite female vocal song.
Saying that I like Adele would be an understatement. Saying that I like this song would be an even bigger one. I have to admit that I only discovered Adele (same with this song) last year, when I saw the Cassie episode on Skins. Indie cred be damned, mainstream or not, I will listen to this song foreva.
