Good analysis of different ways of recommending music -

Ironically, "worse is better" just made the rounds again, this time on
pragprog - http://www.dreamsongs.com/WIB.html and

Pandora

Pandora is pretty good - I'm enjoying it more than Last.fm.  Maybe that's
just because it's newer and I've chosen a different set of sounds, but it
seems to have a wider range.

The "email to a friend" doesn't seem to be working, but you can hear my
station by using "share -> find a shared station" and then entering my
email address.

Gotan Project!

Ha!  Pandora just played Gotan Project's "Chunga's Revenge" on the basis of:

 - Grandaddy
 - Devendra Banhart
 - Cantaloupe Island by HH
 - Groove Armada
 - Tricky
 - Miles Davis
 - St Germain

Sweet!

Algorithm?

Hmmm.  Something I don't like about Pandora is the way it chooses the
music.  Inside of selecting tracks at random that are consistent with my
profile it seems to explore a path through a series of connected works. 
Perhaps this was chosen so that subsequent tracks didn't sound too
dissonant.  But each path (a new path starts each time you object to a
track or restart the player) appears to drift further and further from the
base selection.  The end result is a "radio station" that plays a track
you know, then some pieces that sound derivative, and finally drifts
towards something that you don't particularly like.
