Everyone remembers that "Video Killed The Radio Star" by The Buggles was the 1st video played on MTV. Few people remember the 2nd.
It was "You Better Run" by today's artist, Pat Benatar. While The Buggles really didn't have hits after their initial blast (which was already two years old at the time), Pat Benatar took advantage of the video revolution and built an excellent career for herself.
This song, from the movie The Legend of Billie Jean (also released under the title Fair Is Fair) was one of her last, and biggest hits.
