When the CD first appeared in the early 80s, there was no doubt that it sounded better than the crappy vinyl that was being sold at the time. But over the next few years, a few weird practices started cropping up, insisting that your CDs would sound even better if you did this. I remember two.
First, there was the insistence that if you put a CD in the freezer overnight and then played it, the sound would be much better. Although some people swore by that, it didn’t work.
Another practice involved taking a green Sharpie and running it around the edge of a CD. The theory was this did something to make the red laser that read the CD work better somehow. Sorry, but there was never any scientific evidence that this worked. It boosted the sale of green Sharpies for a while, though.
