Those sun visors (and pretty much any soft case or sleeve type holder) absolutely devoured CDs. I had one too, everybody did, but I only let mine eat my burned CDs (mostly mixes I crafted with cross-fades and normalized levels using foobar2000 and a pirated copy of SoundForge) and carefully curated MP3-CDs. Scratched? Who cares, I burned multiple copies to pass around and trade with friends anyway.
