Thank you for the helpful reply.
So, if I understand correctly, the only practical process is to drag/drop using Windows Explorer from my Music Folder on the laptop to my devices.
And, since I want to duplicate my music/media on 2 devices (phone and tablet), it would be best to drag/drop first to an external drive and then copy everything to my devices.
Something like this...?
Poweramp - Master Folder
Albums Subfolder
Guitar Songs Subfolder (some songs may be duplicated in the Albums subfolder - is that ok?)
Backing Tracks Subfolder
Other Subfolder(s) as needed
Unfortunately, it sounds like a cumbersome process (at least the first time). I have hundreds of artists and a thousand+ albums in hundreds of subfolders (600 GB). I don't want all my music on my devices, plus my sd cards don't have enough storage. I wouldn't do much changing after I get a significant amount of music on my devices.
I came across the app - Droid Transfer - which seemingly has an option to export music from iTunes. But, it is not a media player only a file transfer app. It would still be cumbersome to transfer music, but it would be much easier visually to scroll through my iTunes library and select albums/songs instead of tediously opening folders/subfolders with Windows Explorer.
As for metadata, I think it is embedded in the files. iTunes is just a library, so if I am seeing artist info/artwork in iTunes then I am assuming that that is because the metadata is in the actual music files on my laptop.
If I can do the above folder/file structure with Poweramp on my devices then I do not think I need playlists.
If I want to make playlists can I use Poweramp after my files are on my devices?
My apologies for all the questions. I hope I am explaining everything ok.
Thank you again
