I don't know what modern equivalent is other than playlists for self.
We never pirated or shared mix tapes or CDs.
We only made Audio CDs of our own recordings.

We did experiment with making Video CDs for a while (from live recorded tapes or Off air), but DVDs made those obsolete.

I made some mix Minidiscs, not to be confused with 8cm CDs (AKA mini CDs).
