Most of her songs sound pretty "poppy" like Got Love and Out Of Mind, but iTunes classifys here as "Alternative". How does she sound to you?

lol she's definitely pop and definitely not alternative.

She's already 5 spots higher on pop radio than she's been on alt.

An alt artist would have a hit cross over from alt to pop.

She's closer to pop than to alternative, though some of her songs, especially Habits and Out of Mind, would not sound at all out of place on alternative radio.

Pop, obviously.

I'd classify her as pop, but she's amazing, whatever category people consider her.
