Yeah, this was why I stopped using it as well. It would fall into musical ruts and just repeat the same handful of songs forever. It wouldn't work to thumbs-down those songs because I did like them, but I also wanted to hear new recommendations.

Spotify by comparison will also often recycle stuff I've already heard, but there's still always some new stuff in their weekly recommendations. Sometimes it's a hit, sometimes not, but at least it's something I haven't heard before.
