The Oscar Wilde comment is amazing! Most times, music is a constant backdrop to my day to day life, but others times a mood modifying/uplifting/introspective experience. I remember clearly the first time I heard Barber's Adagio For Stings on a really good system. The music picked me up and carried me away mentally to some other place (almost out of body) and when it ended, the reverb trail of the last note made me feel an inexplicable sense of loss, almost an abandonment that the journey was over. Hard to explain but these moments are what makes all the obsessing worth the effort.
