It kind of failed if you had a fancy CD player (or CD-ROM drive) that could show the lengths of tracks, if every other song on an album is 3 minutes long, then the last one probably isn’t 30 minutes long.
I don’t know what the point of this post is, other than that it sucks when a modern release removes the hidden track 
Remember that you could also rewind into the space before the first track!
I’ve never heard of this before, do you have any examples?
311’s Transistor was the one I remembered. Here are some others: https://en.m.wikipedia.org/wiki/List_of_albums_with_tracks_hidden_in_the_pregap
Interesting, thanks for the info. I didn’t realize that was possible on a CD.
Damn, these two albums had hidden tracks and I had no idea?
