I just downloaded the tracks last night and stayed up way too late playing around with them. There are some weird things with the files, I'm wondering if they did that to weed out the people that'd just bring the faders up and render the mix without much effort. I can only imagine how many entries they're going to have so I guess they've got to have a level 1 filter somehow

Anyways here's a link in case you want to give it a go: https://www.lewitt-audio.com/mix
I've listened to a handful of entries on Soundcloud today. They ranged from OK to pretty good, nothing mind-blowing. But with such a straight-ahead set of rules, I'm not sure how they're ultimately going to judge this thing. They all kinda sound alike (mine included, so far).
