Aye, it's a generous offer, but I imagine most JP fans already have the scores they want (I know I have). Nothing is worth the selling of ones soul to the horrors of Socio-Path Media.
I've been following Powell's career since FACE/OFF, but that is - surprisingly - the only soundtrack of his that I own in physical format. I have 9 more, but they're all in digital format.
I remember after I had seen Face/Off TWICE in the theater in 97/98 I searched high and low for the film With Friends Like These in the video shop only to listen to some more Powell. No luck.
Since then I have fallen totally off the Powell-train though.
