Hi @scifigoth! Thanks for posting your feedback and experience.
Based on your message, it sounds like you aren't able to view all of your stations while using your Yamaha MusicCast app.
Unfortunately, you will only be able to view 95 of your stations when listening on your Yamaha.
There is a 250 station limit on all accounts, free or paid. However, some older consumer electronic devices (such as Yamaha) and car stereos are not optimized for the new station limit and will still be subject to the previous limit of 95 stations. You'll be able to use the Search feature on your device to look for stations that may not be visible.
If you're hearing repetition in your stations, I would recommend trying the following steps from a computer or mobile device. Any changes made will also transfer over to your Yamaha.
Listen using Pandora Modes: When listening from a computer, mobile device, or the Sonos app, you can access Pandora Modes to customize your station experience. You can pick different modes like Crowd Faves, Discovery and Deep Cuts.
Put tracks on the shelf: If you get sick of a track but don't want to give it a Thumbs Down, you can put it on the shelf for a while. To do this from the web, hover your mouse over the album art and select "I'm tired of this track." Pandora Premium listeners should click the ellipsis (3 dots) next the album art to see that option.
Edit your station: In some cases, it might actually help to remove Thumbs Up ratings in the station to mix things up.
Add Variety: To add more variety to your artist or song based stations, you can select additional artist and/or song seeds. You can Add Variety when editing stations.
Running through these steps should increase the variety of the station pretty quickly.
