I love music. My radio stations created reflect some of what I like.
Stations with one * are given that to separate them (when listed alphabetically an * comes before all letters) from "shared stations." The stations with two, **, are given them to separate them from shared stations AND to remind me not to rate any songs I hear on them. This is done, or rather not done, so that I preserve the sound pandora chose for them originally. Especially genre stations....I don't want to taint them with my tastes. Don't get me wrong, I have good music tastes I think but I have a theory that different stations with different themes are at risk of sounding all the same, or losing their uniqueness Because the user has rated so many songs. I want to be exposed to music I know not of. So I take two approaches to accomplishing that:
Some stations I rate songs as much as possible and others I don't rate/rank at all. It seems to work very nicely.
Just some of my internal thinking above.
