Amazon Music Service

Can not search by genre/type in the amazon music service (i.e. New albums in Classical or New albums in Jazz).

New albums search will bring up all new albums in all categories which is not what I want if I am only interested in a specific genre.  Is this a blue sound or an amazon issue ? Not sure. I will bring it up with amazon too if necessary.  The stand alone  amazon music win/android app will bring up the possibility to search by genre but  can't really use it with my bluos player because it does not see the BluOs player/ device so therefore  I have to use /rely on the bluos controller/app to use amazon ultra hd service, but with very limited search capabilities.     Also I noticed that albums/music that will play  in UltraHD in the Amazon music app will only appear as in HR in the bluOS app . Is BluOS player able to detect the Ultra HD Amazon music files and list them accordingly. Does HR listed in the BluOS next to a song captures both the HD and Ultra HD  and in fact it will play the higher bitrate but not necessarily lsiting it properly ? Thanks
