You know that noise in TV soundtracks when someone grabs a tonearm and drags it across the record, then everything stops...

Hold on. I'm pretty sure that in the early days of CD production they weren't low-pass-filtering the tracks before digitizing, and the HF content above 22.1 KHz aliased back down below 22.1 and sounded awful. After about a year all the new CDs were digitized after LPF-ing around 20 KHz, everyone replaced their old CDs (all 6 of them) and lived happily ever after.

This was a while ago but I do remember this clearly.
