I feel a great part of listening to music is trying to out underground the next guy with music knowledge. For many stations, I am trying do that. If I make a station with bands I've found somewhere that have perhaps less than 5,000 followers, it is because I want to listen to that focuses on music that is not popular. How about making a toggle switch for that: one for someone who doesn't care, one for someone who wants to listen to million+ follower bands, 100,000 minus followewr bands, one for 10,000 minus follower bands, and finally one for 1,000 minus follower bands.
