Just curious if every time I press that X, it means I'll never hear a song. Some songs just aren't right for a station, but it doesn't mean I hate the song. Curious if it bans that song forever from all my stations or just one.
I believe the "Never Play This Song" applies to just the one station.
Apple clarifies this in their page for Apple Music Radio - https://support.apple.com/en-us/HT204944
