The song was playing on Thursday Sep 17th in Crossroads Trading Co on Haight in SF. It was a really awesome EDM mix (techno) and almost sounded like a dubstep mix but a little more trance. It was a female singing, but the lyrics were sooo blended in with the beats. It sounded like either "next day wait for change" or "next thing wait for change" and had a dubstep breakdown a few times.

this may be irrelevant but the next song that came on could have been the same artist, it had lyrics w/ a chorus about "kill em til the lights go down"

Please send me any possible matches!!!!!!!!!!!!! thank u!
