Week 4 lesson 2 - random marathon: rand, irand, mininotation randomness, scramble, shuffle, choose + more

@yaxu Could you pls hint why something like this does not seem to work. I'd like to select a bunch of samples for each option or select a bunch of sample folders for each option but I cannot get it to work.

d1 $ s (segment 8 $ choose ["[bd:1|bd:2|bd:3|bd:4]", "808", "hh"])
