The Shelf Life of Music

Does anyone else find it a bit odd that when you first hear a song, while it may not strike a chord immediately, once you like a song you can listen to a song over and over and it still sounds good and, for want of a better word, energises you, then slowly it becomes just a song and that magic is lost? The good news is that if you don't listen to it for a while and go back to it you can recapture it, rediscover why you loved the song enough to own it.

Must be a nice thought for the music industry that we naturally seem to want to consume new product all the time.
