I've created a playlist of tunes that I like to hear...probably about half of them I brought over from my Pandora "likes". The more I personalized Spotify radio (I primarily listen to the "alternative" radio station), the more it just plays the same stuff over and over. Then I go back to Pandora where I've deleted all my likes and am getting fresh(er) stuff. Without killing my Spotify playlist, how can I remove all the likes and personalization and possibly get something I've not heard before? I'm really not interested or have time to root through scores of playlists.
