Does this weird simple hack make compact discs sound better?

I remember a period in the 90s when people swore that there was an insanely simple way of making any compact disc sound better. All you had to do was take a green marker–a Sharpie would do–and run it around the edge of the CD. That green ink (allegedly) improved how the CD player’s red laser read the pits on the disc’s surface, making it sound better.

I tried it, of course. I wanted to hear a difference, but I don’t think I did despite going through a lot of discs and Sharpies. It was all very weird.

Here’s a hack I’ve just encountered: shaving discs. (Via Rick J)
