Hi there stitchingdragon,
We'd like to learn more to see how we can help. Is your husband wanting to access your music library on another computer or on a device like an iPhone or iPad?
To share with another computer, you can set your Mac up to do so in System Preferences:
Share your library with other computers
1. On your Mac, choose Apple menu > System Preferences, click Sharing , then select Media Sharing.
2. Select “Share media with guests,” then choose Options.
3. To require users to enter a password before they can see your shared items, select “Require password,” then enter a password.
4. Select the playlists you want to share, or choose “All songs, movies, and TV shows.”

If your husband wants to access the music on a different device, you can use Finder to sync your music: Sync music between your Mac and iPhone or iPad
Cheers!
