Someone has brought this to my attention, it's called a website.

The Radio Genome Project

type in a name of band
out churns details
of mathematical proportions
on descriptive analysis
matching other musics

i.e. the tullycraft 'station' isn't anything great. it starts with Disenchanted Hearts which is a superfun
listen to, and then first match was Karl Blau, which had me stoked, and ever since then it's been just kinda
like a smilin blah kexp program.

I should type in Holger Czukay. His quote, "I hate music," is classic.

Oh wow, Quasi is playing, that guy rocks.
