I like that you offer the option to change a station to Deep Tracks or Discovery to make it more likely to find either songs or artists that you may not have heard before. It would be great to be able to lock those modes... as in ONLY new (non-thumbed) songs or ONLY new (non-thumbed) artists. Even when in those modes to look for new music, there are times when 3 songs in a row come up that are all thumbed up already.
Moderator Edit: Changing title for clarity
