I've noticed over time weather I thumbs up or down songs that many of the differing stations all start to sound alike. I love a hugely wide verity of music, but when I don't like something I don't like it. So if I'm in the mood for a change of pace switching to another station is supposed to be just that, a different experience. But Pandora's algorithm creates an idea what it thinks I want no matter what station I am on. Journey should be different from Billy Joel Foreigner should be different from Phil Collins Fleetwood Mac should be different from Men at work but I end up with the situation of listening to the same thing over and over again. Even AC/DC eventually started to sound like the others. Try listening to what is the Viking station and you get nothing but English sailor shanties. When do you draw a line and say thumbs up algorithm can't change everything to be identical? Just because someone else doesn't know the difference between music genre doesn't mean I want to listen to the same thing they like.
