Sorry about that! We're under heavy load right now, and there's just a few of us :)
Registration is free though! Then you get more free sessions.
I hear we're planning on creating a longer trial program soon. But until then, I hope you'll give it another try.
For the record I don't really mind if people use it incognito, BUT it will keep giving you the same sessions over and over. So you're not getting but a fraction of the experience. We just need the survey so we can better adapt to you, and for benchmarks later on. It really doesn't take long. Also if you have an account it will adapt to you using ratings and other metrics, like if you skip a song consistently, etc.
So, I get in the zone and then click! internet error. Had to refresh, and now it demands I complete a survey and register... grumble grumble. :/
Cool site though, good luck.
