I can't find a song
 

hey guys so I used to love this song and I cant remember the name of it or the singer! its so annoying I remember the video though. I know its kind of impossible if you have no lyrics or anything! there were lots of lights kind of like fireflies in the video. I think she was singing in her bedroom? she looked kind of emo/punkish? she has black hair and a side fringe? the song was kind of electro?
can anyone think or remember her?

Is it by any chance the song Saviour by Lights??
