Hi! I'm looking for a song that would be considered a bit outdated now. I remember the melody pretty well, but I'm afraid this song lacked a substantial amount of lyrics. It seemed to be a trance, progressive house, and ambient chill type of song with a female vocalist. I heard it several times in a couple of different stores, Forever21 and Macy's.

I can't remember what she's saying, but I remember that she sang with the melody and her words fell in like this: ___, ____, ____, ____ lalalala, lalalala
___,___,___,___ la la la laaa

and then it would return to music.

I'm soooo sorry I can't remember the words. It's been a nightmare trying to find because all I can go by is the music, and none of the voice search songs seem to be able to pick up the song, as all I know is the chorus. I can hear it so clearly in my head, too, but not the words, only the melody.

In short:
The song was played in Forever21 and Macys between 2007-2009
It's a female vocalist
It's kinda trance/progressive house/ambient and echo-y sounding.
There's few lyrics, save for the four ooos and lalalas that I recalled above.
I still remember the music, so if you have any idea, please let me know. I'll be actively checking around.

I searched through most of the Forever21 lists and haven't found it yet, but maybe someone else was looking/or is looking for this song too. Please help if you can. Thank you so much!
