I dunno how old this is but I feel like I've been using it to discover music since I was 15 or something? Years ago I discovered Camera obscura via Belle and Sebastian and fastball and I've been listening to them ever since.. I also thought it was called the Global Network of Dreams. It's a pretty awsome tool.
Yup, your feeling is correct. When I wrote my first self-learning discovery tool, it was the one that asks the visitor for 3 bands and then suggests other bands based on what it learned so far. And for some reason I called it "Global Network Of Dreams" at that time. Glad it worked for you!
