Over the weekend I started playing a game in Spotify.
The idea is to start with an artist, and get to another artist through Spotify's "Related Artists" concept. A little like 6 Degrees of Kevin Bacon.
It's fun, and you can add to the interest by playing a track as you pass by each artist.
As an example, to get from Green Day to Elton John, follow this route.
I also play that you can't use the Beatles, as they're probably at the root of a lot of bands.
I wondered if anybody else had come up with this game, and found a similar idea here.
