Hi @cyprus257. Welcome to Community! I moved your post to the My Collection space to keep things organized. Thanks for reaching out, and I can understand how frustrating that would be—especially when you're using your station to practice and study Greek and are hearing songs in other languages instead. At this time, there isn't a way to filter a station by language, so while you've seeded your station with Greek artists, there isn't currently a setting that guarantees only Greek-language tracks will play. I've noted your request for a language-filtering feature and appreciate you taking the time to share that feedback. That said, if you're hearing tracks that seem out of place on your station, we'd be happy to take a closer look. The next time this happens, please give the track a Thumbs Down (if possible) and send us the following information: • The name of the station you were listening to • The date and time the out-of-place track(s) played • The name(s) of the out-of-place artist(s) • The title(s) of the track(s) that played • A screenshot of the Now Playing screen showing the track • Whether you were able to give the track a Thumbs Down • Whether you were listening in a Pandora Mode such as Crowd Faves, Discovery, or Deep Cuts Once we have those details, we can investigate further and determine whether those tracks belong on the station. ...
