Help with this song- piano at beginning with a female singer

Whose this artist and song?

OK, I know it's a long shot because I don't know the lyrics. haha but I was hoping you could take a stab at this type of singer atleast. She has a style of music which sort of sounds like Anna Nalick to me. She sounds like an indie/folk singer. Her voice is calm and it's sort of high. It's definitely not low.

Someone told me her name before and I completely forget it, but here's what I do know:

1) It's a solo artist
2) She isn't too famous..I had never heard of her before.
3) It's a pretty current song.. couldn't be more than 6 or 7 years old. Could be 6 months old idk lol.
4) There's piano playing in the beginning and it is so catchy! It moves quickly, although the song isn't a fast song. I can hear the piano in my head "bum, bum, bum, bum, BUM, BUM, BUM, BUM bum, bum, bum, bum, BUM, BUM, BUM, BUM"
so yeah that's two counts of 8 of quarter notes and then that tune repeats again (I think)
And then she starts singing and the piano plays through the whole song. I don't think drums, or guitars, are in it.
5) I heard it in my lyrical dance class when we were going across the floor
6) It's a really pretty song

So it would be amazing if you knew what I was talking about but atleast take a stab at the singer:

*Who is a singer like anna nalick or sara bareilles (without the pop/rock vibe) that isn't too main stream or famous who uses mainly all piano in one of songs. If you could narrow it down to even like 3 names who vaguely fit this description that would be great!

Try Norah Jones. Most of her songs have a piano intro.

I joined this site just to reply to your question haha...

Omg this is the exact song that I'm looking for! Did you end up finding it or perhaps the name of the singer? I want to use it for a lyrical piece and I'm struggling to find it
