So @anon43302295 we meet again 
This is a script from @Bob_NL (Chromecast Radio with station and player selection)
I’ve implemented it on my setup and it works, I don’t have as many stations, but I believe @Bob_NL does
@maurizio53 Can you try and remove some stations to test @anon43302295 suggestion?
I copied your code in Notepad++ and indentation appears ok…
