help me find this song please!

I was recently in forever 21 this past week and i heard a song that i really like but i cant seem to find it anywhere...unfortunately i wasnt able to hear the lyrics that well but it was a woman singing with a soft voice, it kind of reminded me of ingrid michaelson...and i think some of the lyrics are "as long as you can" not totally sure if thats right but i think it ended in "can" sry im so vague lol idk if this would help but the other songs on the mix were the ting tings "shut and lt me go", "elvis aint dead" and some song that said the word guilty alot....if anyone by some miracle can help me, please let me know! lol thankss :-)
