To burn CDs is to write music onto a disc that nobody can take back. A laser heats a dye layer, the dye darkens, and the pattern stays there whether or not the artist stays on a streaming service, whether or not your subscription renews, whether or not the album gets re-licensed next year. That permanence is the whole reason people still burn CDs, twenty-five years after the format peaked.
This page is a practical guide to burn CD projects of every size: the hardware, the blanks worth buying, the software on each operating system, and the four or five settings that separate a disc your car reads instantly from one it spits straight back out. If you have never done it, you can burn CDs successfully on the first attempt — the process is forgiving once the important decisions are made in the right order.
Everything below assumes you want playable discs rather than theory, so each step is written the way you would actually burn CDs at a desk with the drive humming. Where a step matters, we say why. Where the default is fine, we say so and move on.
