Yeah, I like that – I think that’s what’s exciting about it.
Also, like you say: “current most basic” – the blog structure (of one-track linear time / current / history) isn’t *the* structure of music or the creative process, and it can be a lot of structural / procedural baggage around music.
And, e.g., look at MySpace as an example of how a different, but very basic structure (a page with 4 tracks and a player) can work for both musicians and listeners.
Mostly aside: I was just thinking, someone could create a webring-like music format, e.g., post a track on a page, and have that page link to prev / next track, across the web. We still need a web music player that works more like a spider, and follows links. . .
