A new video matches - almost to the second -- Swift's new song "Shake It Off" with a dancing video of 1989 Crystal Light Aerobics Association's U.S. champions.
The video, not light on the spandex unitards, glistening pearly whites and overblown enthusiasm, is so 80s. The aerobicisers clap, pump, and shimmy so enthusiastically to the song that it's hard to imagine they could be dancing to any other music.
The best part is this video is from 1989, which is the year Swift was born and it's also the title of her new album.
