My Question or Issue

I use the Spotify Statons for a week now. Impression is not bad, but it needs improvements :

1. thumbs up a song switches to "Favorites" radio (that is already reported by antother user)
2. It repeats songs. Sometimes the same song as Radio/Live Edition, sometimes it just playes it again. Is there o maximum number of songs that you can get, if you would play the radio for 6-8 hours with several artist ? I really won't to get new songs, especially with similar artist - I don't track music market so I'm not familiar with new artits on the martket and with new albums of artist, that I know. 
3. I would like to have stations in regular Spotify app . In the Spotify Stations I cannot use Apple CarPlay, I cannot get more info about song/album etc.

Best regards
