Back in the day, Pandora showed you the attributes that they had tagged each song with (stuff like "down-tempo funky grooves", "offbeat emphasis", "prominent female vocalist"). I always wished there was some way to create a station based on an intersection of attributes, rather than a union, when you add multiple seeds to a station.
I had an ongoing email dialogue with the Pandora CTO about this feature. Soon after Pandora's launch he said the future was coming soon but several years later he said that the way they had set up their database made it impractical for them to actually implement this feature.
You can do this. In the song you like, click on a tag to create the station. Then under the station preferences you can add variety, such as an artist, genre or another tag.
Not quite what he's looking for. You can add more variety to make a station of music that includes x OR y OR z, but you can't make a station that plays songs with x AND y AND z.
I've run into this as well. You try to make a station that plays piano rock, and Pandora goes "Hey, here's a song that fits! It has: 1) mixed acoustic and electric instrumentation, 2) major key tonality, and 3) mellow rock instrumentation." It won't care that every song you've added to the station was tagged with acoustic rhythm piano, all tags are equal to the matching algorithm.
