What Is Song to Sing in the Car?

Songs to sing in the car was just one play list among thousands and thousands of editorial playlists. We wanted to deliver music that was familiar to people, that they know all the words too, and that they'd want to sing along too. Without personalization, we just had to rely on the hits. So what are the most popular songs that are also the most singable? And then for sequencing, used our personalization algorithm to kind of really scale that out.
