This app seems like it's still in Beta form. Using it on my AppleTV, I chose to create an '80's station by choosing "80's" under "Decades" under "Genres". All it does is play the same songs over and over again, by the same small group of artists. Tried adding about 8 different artists that were big in the '80's it wasn't playing and it doesn't play them. Have it set to play only "Hits" but, it keeps playing tracks from albums that were never released as singles. Sometimes, It will play a song, and then play it again after only playing one different song in between. Sometimes, I've told it to never play a song, and it's played it again in the same fashion, and I had to tell it to never play that song a second time. It will also play the same artist twice in a row. Pandora offers a better listening experience at this point. Apple really needs to do more work on it's algorithms.
