I am having great difficulty with Play Music APP, and am trying to download songs from my library in the cloud, to my phone, and Samsung Tab, and also the same to my fathers same Tablet for his music collection. I have a large collection of music on my PC, and have a small portion of that uploaded to Play Music. They are visible in library on my devices. I can select songs and albums individually to download, but that is far too mush hassle I want to update/sync all by selecting REFRESH [is this what this should do, as I can't find it explained (note to google) anywhere very well?]. So why when in Play Music can I not hit REFRESH, and at all sync down to devices???? Please explain or send me a link.....and I have read all the google stuff on this, but it is poor!
