I run Jellyfin, but I’ve got a similar situation with our music library. Mine, my mom’s, my sister’s, my wife’s and her mother’s music has (mostly) all been uploaded to our Jellyfin.
Before I got married I used to say my music library had everything from A to Z. With as diverse as our tastes are that may now be close to being true in fact.
Jellyfin has the ability to favorite artists, albums and individual tracks, as well as the usual playlist functionality and that has helped a lot. My wife makes big use of the collections function as well.
