How to determine where music in iTunes Library originated

I have multiple entries in my iTunes Library that I would like to determine where they came from or how they got there. I know that I have acquired some tracks &/or albums from Apple Music while the rest of them I have either ripped or purchased online. The reason for asking is that I am contemplating dropping Apple Music as a cost saving measure & I would like to know ahead what is going to disappear....

Thanks in advance...billgr0248
