Song in H&M

I heard this great song in the Atlanta H&M. it was upbeat and by a woman singer, and it was sassy and about "i'm gonna make you fall in love with me" or something. And one of the lines went something like this: "monday, tuesday, wednesday, thursday, friday...."

Oh, and it was NEW, not from the 90s or anything. It sounded like Beyonce or something...
