it works really cool, you can just start with any song. I took some song titles from the "name that tune" thread. Then it plays that song and then automatically starts playing other songs like it.
I am discovering a lot of nice songs that I never knew about before with this setup. It plays in the background and you don't even have to watch it so you can work and do other things. I like it just so I can discover new songs and be a self made 70s kid like you guys.
