Amazon music add to playlist and credit

I am on Amazon music which provide as good quality sound as Qobuz and Tidal… but I am disappointed by the features given through BluOs… I do not have the :. Menu Possibilities to add the song playing to a playlist or to see the credit about the song… this is really a pity… as more and more people are on Amazon Music… anyway thanks to Bluesound to give the possibility to work on Amazon Music, this is a good choice compared to Rose system which do not support this music streaming provider !
