If I had to just choose 10 discs, I probably wouldn't choose any. I get tired of anything over and over again.
So you'd rather have no music at all?
I understand your point - only ten discs would be very limiting. That's why most, if not all, of us own way more than ten albums.
But I'm sure you'd agree that some of your albums stand up to repeated listening better than others. And some of them are just so good that you'd want to be able to listen to them once in a while if you were stuck on a desert island.
So, the way I see this exercise playing out, I hope you have fun in a world where the only music you hear is what you can hum in your head. I can do that too, plus, I can listen to one of my favorite albums once in a while. Neener, neener.
