If you are into chiptunes (that old computergame music) I recommend checking out the Mod Archive: https://modarchive.org/
It’s a compilation a of different Mods and XMs (Files in which the 8-bit-tunes come) which can be downloaded and then be played with FastTracker (available on https://16-bits.org/ft2.php) or the XMP Xmod-Player under Android.
On Fedora check out MilkyTracker
