Find my ripped music?

Replaced a 10 year old iMac with an M2 Mac mini and intentionally did a fresh start (ie, not a migration).

What is the best way to filter and then transfer only the music I ripped from CDs (100s of songs)?

Because the iMac’s storage is a Filevaulted external SSD, my thought is create a filter in the iMac’s Music app, then AirDrop to the new Mac mini. What I mostly need help with is what to filter on in the Music app to find only ripped music.

Thank you in advance!

I think you are on the right track. Here is my Smart Playlist for purchased music:
