This article is pretty awesome! Seanbaby inputs Sussudio by Phil Collins into Pandora, and sees what songs come up, making the song that comes up his next playlist. After 6 degrees, it leads him back to Sussudio.
Hey, How about I give it a try. I'll start with
The Spirit of Radio, by Rush.
1 degree: Wish you Were Here, by Pink Floyd...it mentions this is due to complex guitar lines and "great lyrics"....
2nd Degree: Paint it Black, The Rolling Stones, due to mild guitar buildup, heavy syncopation
3rd Degree: Won't get fooled again, by The Who, for subtle vocal harmony and an emotional male singer
4th degree: A day in the life (love version), by the Beatles, for gospel influence (?)
5th degree: Black Tables, by Other Lives, for minor key tonality and acoustic guitar
6th degree: Little Cloud, by the Whitlams...
I went in 6 degrees from a guitar driven hard rock song to a piano driven soft rock song from a band I've never heard of...
