It's a song that I believe is currently popular because I've heard it before in commercials. Just a while ago, I heard it during a transition from the Ohio State/Northwestern game to commercial (in case anyone else is watching and heard it). It's got an upbeat dance beat and a woman singing. The only lyrics I can remember are something about "the lights" and a long "oh" right after, or maybe it was two of them.
I should add that the "the lights" part I remember was in the chorus of the song, and it was at the end of a line. Like "_____________ the lights __ ohhh."
I should also add that after playing around with my piano app, I've got a G for "the," up to A for "lights" and down to E for whatever preposition comes after. The "ohh" is a melisma that I remember as something like DEG. (likely not the actual notes, but intervals sound right)
Edit: It's not "Lights" be Ellie Goulding. I am terrible with pop music, but I do happen to know that one.
Edit Part 2: It's "Applause" by Lady Gaga! The part that goes "Give me that thing that I love (I'll turn the lights on)." Thank goodness, because I was seriously going to stay up all night looking. Thanks for all of your help, guys!
