Luke13th. I think I did this right.  I clicked on the little window on the bottom left corner and brought up all the AAPS.  Went down to setting and open it up.  It brought up Windows settings.  I clicked on APPS uninstall, defaults, options features.  Then I clicked on Default APPS went down to music player.  There it had Groove Music, so I clicked on it to display Groove Music, Media Player by Medialinkand  Windows Music Media.  I have Windows Media Player APP on my desk top.  Do I need to change the APP in APPS Default to Windows Music Media? 
I thank you for your time.
