Okay, i don't have much to go by but i will try my best. This song is from the mid 2000's. It's a pop/r&b song. A girl sings it and some of the lyrics are, "there's just one thing that i kept thinking" or something like that. I just remember she has black hair, she kinda looks like the main girl from the pussycat dolls. In the video, its her and female dancers ( i think) and she is wearing some type of fishnet leggings and she has super long black hair. Anyway that's as much as i can remember. Sorry.
