Want to feel really old today? If you miss the sound your cassettes made, but have MP3s on your computer, you’re in luck. Don’t waste your time hunting down blank cassettes and broken Walkmans on eBay. If you’ve got a browser and a web connection, a simple site called WebCassette will load and degrade your digital music files so the sound quality hearkens back to a time before compact discs hit the market.
