I started a playlist 10 years ago, one genre of music, Jpop. As time went on, I added Kpop. It took time to cultivate this playlist, and alot of patience. Now Pandora keeps tossing american hip hop in the que. I have decided to part ways with Pandora and will be trying new apps. My warning to anyone new is after you cultivate your playlist over time, Pandora still won't get it right.
