Looking at the error messages on Console on my MAC, I discovered some errors on some audio files that say:
Error opening the FLAC file for decoding: file=file://%2FVolumes%2FAudio2%2Frock%2F1001%20Albums%20You%20Must%20Hear%20Before%20You%20Die%20%28vol.I%29%2F0066.%20The%20Kinks%20-%20Face%20To%20Face%20%281966%29%2FThe%20Kinks%20-%20Face%20To%20Face.flac error = 4
That’s pretty strange! I tried to play the audio files in that very same directory, and it works. I don’t know what is error 4 and I did not see any clear impact on the import process.
