I have been trying to think of this song's name but can only remember the music video not the song, in the music video it starts with a woman with an afro walking down some stairs then troughout the vidoe she starts stealing things from men and the end of video she knocks out some guy and then leaves. Believe the music video was meant to be set in the 70s/80s but the music video has been out only during 2016/17.
Try to remember some lyrics and search it on streaming music services, like Spotify or Google directly. When you get the song name, you can download it with your premium account. If you don't have one, take Spotify as an example, you can use DRmare Spotify Music Downloader to download your song offline, even save them as a common audio format.
