I finally made a CD with 98 tracks on it. It was all radio spots that needed to be dumped from 1/4" tape to CD. If I hadn't caught some redundancies, I would have needed to make two CDs even though there's less than an hour of material.
It's a while since I've seen this, but it wasn't uncommon for early classical CDs to have things like individual concerto movements indexed within a single track. I believe some older SFX CDs may have used them too.
