Sooloos does not read or rely upon the embedded ID3 Metadata Tags when Importing either Flac, WAV or any other files
Are you absolutely sure?
I recently ripped a sampler CD. I had to edit the Tags manually with "Tags.App". When I imported the FLACs using Control:Mac the Track info had been picked up from the FLAC file. Its the only place it could have. The track names were 01 - Unknown Title.FLAC etc
I have read on the forum before though that Sooloos ignores embedded meta. It just at odds with behaviour I have encountered.
I have had other albums that have been "difficult" yet a little massaging with the Tags and they have imported ok.
With the issues the OP has been having, I feel using WAVs is a major contributor and trying a FLAC conversion could help. Happy to be proved wrong. But given the classical CD mentioned appears to have surprisingly good AMG data, Im surprised it won't import.
IMHO, the algorithm used by Sooloos is too finicky and only leads to user frustration
I couldn't agree more. But then Hitchhikers are probably at the obsessive end of the spectrum of Ms target customer these days.
But given the number of posts this subject generates, a bit more information could possibly be helpful
