If you asked me to pick five cds to take with me for an extended sojourn on a deserted island, I would ask to trade them for a roll of toilet paper.
After several weeks of listening to only those five cds, I would be so absolutely sick of listening to them that I would probably never want to hear them again. I would far prefer to listen to nothing and enjoy them for the first time all over again if/when I got home.
If cds burned, I'd take them and use them for kindling. But they don't, so that'd be kinda useless. Maybe use the discs as cutting tools. Maybe use the liner notes to wipe my ass.
