Audio CD track names cannot be imported in WaveLab anymore. Despite having internet access, the following error message appears:
A problem with your internet connection occured.
The track info could not be updated.
FreeDB, the music database WaveLab relies on, shut down in March 2020.
Since then, "Find track names on the Internet (FreeDB)" in WaveLab is broken.
For the time being, we can only recommend to import track names using software, that doesn't rely on FreeDB. For example, iTunes ("Apple Music" in Catalina) is using the database Gracenote.
Unfortunately, at this point, it cannot be said yet how and when the import of track names will be available in WaveLab again.
