Yeah, I'll second the fact that Mr. Seoafs is a cool cat. He can rub you the wrong way at first, but after you've been around a bit and get used to his style, you can't help but like 'im.
Six Degress is a song. But it gets confusing for a number of reasons. First off, it's over 40 minutes long. There aren't a lot of songs you can say that about. Second, each of the movements is about the length and structure of a more traditional song. And to compound the issue, the band has played individual movements as standalone songs in concerts, and has created edits of two of them so they can be played as individual songs. So, yeah, there are a lot of good reasons to not think of it as a single song composed of many movements, even though it is. At the end of the day, if someone subjectively wants to consider it a suite or a a group of songs, or something else, it doesn't really matter. And I don't think anyone in the band really cares either. I think they're just happy that it is a piece of music they are proud of, that a lot of fans like, and that fans talk about.
