MP3 killed the hidden track

In the early 90’s, it seemed like every CD’s last track included either a wacky cover song, improvisational acoustic number, or musician shenanigans recorded in the studio, hidden after minutes of dead time. While it went out of favor a few years later, it still pops up every now and then.

Today I found myself listening to a mp3 that featured 8 minutes of dead silence before a half-finished song popped up and I realized it’s probably one of the only mp3s I own that features such a thing. It makes no sense to have 5 minutes of music (total) take up 15 megabytes (mostly of silence) due to the hidden nature of the last segment. I’m curious if the advent of mp3 did anything to speed up the death of the hidden music track or if I just fell out of favor naturally.
