Me too. Twice. I first started using it five years ago when you could download the tracks right off the site. Was really the first time I started listening to music outside mainstream radio type shit. Then they changed things up and I stopped using it for several years. Then I rediscovered it and it changed everything again.
I start having panic attacks if I can't go through it every couple days. (What amazing tracks am I missing right now!!! must have internet!!)
