Hiya
Now I don't hold much hope of finding this song, but the board has show some amazing skills in recent years finding songs with the smallest amount of info you can imagine.
Without further ado, I've got the chorus of a fast paced clubby/trance song in my head. With a female singer, who I think sounds similar to the one in this song
The lyrics as best I can remember are something like:
I wanna/want to be
lay/stay forever
be together
Best guess I had was truly madly deeply by cascada but it isnt the one i was thinking of!
