Hello,
I am sure this is a well known problem but I did not find the answer in the forum.
I digitalise existing CD into Flac and I use Groove (on W10) to read them or BlueOS (from my NAS)
For compilations :
- Sometimes I see all the different titles from different artists under 1 album (as it is physically organised mimitising the physical CD) and this is what I want
- Sometime every single title appears as being 1 album...
I digitalise the CD the same way, organise them the same way, and - although I had a look at the tags within MP3TAG - I do not understand why I have different results for something that appears the same to me.
Example 
- wrong case : all songs as a different album monCIO
- right case : all songs under a single album monCIO
Any help will be much appreciated.
Regards
