Has anyone tried to create multiple channels with Pandora, to see what kind of music is "like" a particular composer, group of composers, or style of music?
Here's what I've found:
Successes
Space Music. Seeds: Philip Glass, Robert Rich and Steve Roach, branched out into Brian Eno, Terry Riley and even some Moby. Most of my thumbs-ups are by people I've never heard of. I find I need to be eternally vigilant that I don't end up with too much cliched New Agey crap - tweeting birds, babbling brooks, Indian flutes - but overall, I've created a nice, consistent station that plays music that I think of as Space Music.
Thelonius Monk. Just starting with that one artist, Pandora quickly found all the compatible folks: Art Blakey, Charlie Parker, Chick Corea, John Coltrane, etc.
Failures
Gerschwin and Impressionists. My experiments to start with George Gerschwin for one channel, and Impressionists (Debussy, Ravel, Faure, Satie) for another really haven't yielded much more than the composers I started with, plus a bunch of stuff I keep voting thumbs-down on. Maybe my categories are too narrow or Pandora's library is not broad enough.
Nuisances
For many of my stations, I am continually having to evict two formats that left on their own would grow like weeds to choke everything out: Film Scores and Classical Music. The complication is that some Film Scores do fit well in some channels - Philip Glass in Space Music, for instance. I think Pandora puts too much weight on Film Score as a category. If you like a score by Philip Glass, pretty soon John Williams is trying to horn his way in...sorry, Star Wars is the polar opposite of "Space Music," ironically enough.
Verdict
It's very easy to create nice Classical and Jazz stations, but what's the point? Just use iTunes to find a radio station in that style. Where Pandora excels is in creating very finely tuned stations for more esoteric tastes than can be found on iTunes radio, as long as it's not so esoteric that it really isn't a "category" at all.
