Quoted from HoakyPoaky:
Repetitive play is stagnant play IMO.
It's a catch 22
I originally did not care for the linear modes on Ghostbusters-then as I got better and progressed further it became really rewarding and now getting to Stay Puff feels like a true accomplishment. Sometimes GB can be a bitch and really kick you in the nuts with drains. I now would not want GB to be random-it would lose the challenge for me.
I think the same will go for LZ, although I would not be surprised if they changed code to random to appease the location play people who want to hear other songs.
I would prefer it stay as a ladder style mode
