Getting my music ripped to iTunes

What exactly happened?

Is the Music Library empty on the Mac with Catalina?

Does the Music App issue an error?

Are you not aware iTunes was replaced with the Apple Music app on Catalina?

You need to explain exactly what is happening if you want any kind of advice.

See the 'Restore an older version of your library database' section and others) in:

Empty/corrupt iTunes library after upgrad… - Apple Community

That depends.

What happened to it?

Do you have access to the computer it was stored on?

Provide some details and context, and someone may be able to advise.
