Discovery mode is my preferred mode of listening because my threshold of boredom for hearing the same songs over and over is pretty low.
However, I have noticed lately that something like 75% of the tracks Pandora is playing in my discovery station already have my thumbs up on them. I have resorted to "I'm tired of this song" over and over.
Is there some way to tune this discovery algorithm so that it really does play songs or artists that aren't normally on my station? Or a new mode of "no repeats"?
