I just heard "The Heart Wants What It Wants" from Selena Gomez.
I like it a lot. (Is that bad?) It's gross that it's about Justin Bieber, though.
In any case, there's such quality to Selena Gomez' voice. It doesn't have to be powerful or quirky -- it's just effortlessly natural, sweet, smoky, honest, and beautiful. Too bad the majority of her music is badly-produced, but "THWWIW" is pretty good.
