I did this in 2024! I use Finamp on my phone for music.
I bought a lot of albums on bandcamp, bought CDs for those that weren’t on bandcamp, and pirated those that weren’t available in either format (looking at you still woozy, stop releasing tapes lol).
Used CDs are a great deal and can be shipped all over the world for cheap.
Users on jellyfin can be allowed access to selected media libraries so just divvy stuff up that way, simple as folders.
To be a little more specific, schools take a cut (often called overhead) of awarded grant money to pay admin salaries among other things - sometimes in excess of 50%!
These rates have grown universally over time and the practice is obvs not popular amongst the actual researchers/PIs.
