Finding good music.. that second or third play of that song or album - when you're on your way to that euphoric peak of early enjoyment. Deep into the track.. before it becomes a number in your collection that you can't help but overplay (because you love it so much) or sort of forget about, or one day discard as "un-cool".. Deep into the track.. early on. That's when music excites me like nothing else. So there you go.
