@Thunderchild: To each their own, but as a choral singer myself, Rarity's singing voice is simply too refined, mature, and all around technically sound (to say the least) for me not to love it most of all the Mane 6 singing voices.
@Batbrony: I wasn't comparing singing voices as much as general attractiveness-and a nice singing voice doesn't make up for all the other high maintenance stuff she pulls imo.
