nas Synology and volumio primo
Question how to arrange my music data so Volumio (or bliss) can read it
found proposal : ‘YourLibrary/Name of AlbumArtist/Name of Album/Songs’
is example correct pop/Peter Hammill/Peter Hammill- love songs/ flac + map albumart with folder.jpg
or pop/Peter Hammill/ love songs/
classic/Beethoven/Beethoven - Late String Quartets/ How to solve problem with more than one cd ?
Where to put picture of the artist?

Best to download MP3Tag
www.mp3tag.de

Then just edit the tags as you wish, including adding album art work.
I’ve used it to edit all my 5000+ albums.
For me it was very time consuming, but worth it in the long run.
At least I now all my files are tagged correctly.
