Before I got into DVD's, when they were pretty new, I kept hearing about how the real treats were when there was an isolated soundtrack on the disc; where you could just listen to the soundtrack without watching the film. I have a good 40 DVD's now (c'mon I still have a budget) and I don't have one with an isolated piece of music (unless you want to count "My Heart is an Island" from Swiss Family Robinson). Do they do this anymore? I can't remember which films I heard had this and I don't know that they were any I would want anyway, but it would seem that this is something that's been discontinued. Any info?
