so what time do you all think would be best to get there. I have never been to one so I would assume people wonder in and out throughout the day. Are there generally more set ups morning, afternoon, ...most people out by 2,.... Also, I was thinking about making an assorted playlist of like 5 or so songs on my zune to test these with (hi, mid, low, voice, fast, and slow). Are most people good with letting you change the source or should I just listen to what is set up?
