edit : I just logged in and noticed that I can upload a song a day on top of my limit, so some of my criticism is invalid. Thanks for the change, and for the advice!
I posted some songs to thesixtyone (http://www.thesixtyone.com/#/nihilocrat/) and wasn't happy with the experience. I'm guessing it's my own fault for sucking, but I do have to fault the site for having a "winner take all" attitude towards artists.
You're in a bad situation if the public doesn't like the tracks you post when you post them. You're practically invisible if you don't get lots of votes immediately, appealing specifically to thesixtyone's community tastes. I don't mean to whine, but I don't see hardly any downtempo/triphop with lots of bumps and thus there's not much encouragement for someone producing such tracks to post on thesixtyone.
To the victors, the spoils, but it's even more humiliating when you're unnoticed and forever stuck at Level 1. thesixtyone is definitely a listener's site (duh) because it doesn't encourage you to post partial songs you are working on and practically no one gives you technical criticism, merely things like "I like it when the song gets heavier in the middle". No one seems to be iterating on their tracks but instead submit only complete ones. Please excuse me if my anecdotal observations here don't match up with any metrics you've put together, maybe I have tunnel vision because I listen almost exclusively to the "dance" and "electronica" portions of the site.
About the Level 1 ghetto, is it meant to encourage us to just start over again with completely new tracks or is that just a side effect?
Even with these reservations, I think thesixtyone is a great music site with a great community.
