How to get iTunes Subscriptions and Playlists accessible to two different Apple Accounts?

Before I mistakenly used my iPad backup to revert my iPhone to a previous date my husband and I each had our own Apple ID but shared his for iTunes and subscriptions so purchased ringtones, playlists etc could be shared and I paid for our subscriptions. I’ve got everything straightened out now with the exception of the shared iTunes and subscriptions. Anyone know how that was set up to be shared? I had my own Apple ID but we only have and shared iTunes on his. It was done by someone at the Apple Store originally but when I asked recently I was told we needed family sharing because that’s how Apple wants it done now, but purchases cannot be shared that way and I’d have to create all new playlists which would be very time consuming when we already have them made on iTunes.
