Looking for a certain music video. i know visuals, but not the artist or song name.?

Question

The video is one by a fairly young male musician. In the video it is all of the artist's grandmother dancing to his song. She is exercising to the music, dressed in workout clothes, probably in her 80's or so. it starts by her hitting play on her stereo, and the rest of the video is of her dancing. it was a cool song, and if anyone knows, you get 10 points for letting me know!! have at it!
