Her music is like one size fits all for me. If I'm happy, sad, running/exercising, dancing, getting tipsy, driving... I mean, her music is appropriate for everything.
Then of course there's her beauty, her charisma, how funny she is, her dancing talent, her energy on stage, her angelic voice, how down to earth she is, how hard-working and goal-oriented she is, etc.
I mean damn, she's as close as you can get to God.
