I never really traded with old CDs. I rather just gave them away for free to people remotely interested as I am always happy when people listen to movie scores.
The idea was downsizing of stuff I rarely listen to.
Yes. The space topic. The only time I regreted a little giving away CDs was after I had given the first three Harry Potter albums to my piano teacher after I had purchased the 7-disc Harry Potter box from LaLaLand. I thought, I don’t need them anymore because now I had the complete thing. And I would still say, that’s correct related to the first score. But for the 2nd and 3rd I’d rather listen to the OST as these flow much better.
But regrets in context of film scores I rather feel when I think about not getting certain albums at a time when they were still easily available.
