Pandora's repetitiveness can be frustrating at times especially for long time users of the service. The best option I've found found when creating new channels is to use "Add variety" and avoid the thumbs up / down rating. In this way I still hear new music and although there are repeats those are fewer and far between. If I want to tailor a station to genetically similar songs I then use thumbs up / down.
