Minidisc was a HUGE commercial flop, with a paltry number of releases. It found utility in some pro audio racks but in no nation did it ever come close to replacing DAT in pro audio applications, or cassette tapes for music copying or distribution.

What I remember from my minidisc days were that at least the ones I owned were all recorders. Even though I bought zero minidisc albums, I had a few minidiscs with albums recorded from CDs.
Even though minidisc wasn't ubiquitous, I'm not sure that the number of releases is a good measuring stick.
