Seandtaylor99 - I agree with your percentages - that's exactly how I'd break down my CD collection. There are definitely CD's I'll never put on again, but it's a small %.
I disagree that alcohol can't improve a bright, overly-compressed recording. If it changes your mood, lightens you up, and gets you to take the focus off the recording and put it back onto the music, it has "improved" the recording. Drink enough, you might get out of the sweet spot and dance around the room :-)
