Love her single (I didn't just hear it, lol, I'm just saying). Another song from the album that I really love is Set Fire to the Rain. Hope it's her next single.
Though in all honesty I really thought she was older than 22. Not sure how old I thought she'd be but older. I don't mean it in a negative way either. As much as pop stars like to act like they're 18 even when they're 95 (I'm looking at you Madonna), I think Adele's maturity is really refreshing.
