>> anyone who has used AccurateRip can probably testify that CD ripping errors and manufacturing errors are surprisingly common.

CDs have significant error correction codes so if it sounds right it IS right. Having said that, I have one song I always skip because it ripped badly and I've never got around to re-ripping it and replacing the bad one. But it's obvious that it's a bad rip to the point that I skip the song so I don't have to hear the glitch.

In other words, if they checked each song before uploading it would be fine.

For data CD formats, yes. For audio CD formats, readers are allowed to interpolate over uncorrectable errors (https://en.wikipedia.org/wiki/C2_error), which would not necessarily result in an abrupt skip or pop.

No, player will interpolate samples with detected but uncorretable errors. Uncorrectable error rate of CD-DA was deemed too high for CD-ROM, thus it uses additional layer of ECC data on top of it.

Heh. I have one that has about five seconds of silence, at the end of an album, then about ten seconds of horrifically loud noise. It still catches me off guard every time, but it’s not in heavy rotation so I still haven’t gotten around to trimming it.

I wonder if this is why there is a Dinosaur Jr song with a massive bad-rip hole about two-thirds in, on all the streaming platforms.

"""A plus indicates not only frame jitter, but an unreported, uncorrected loss of streaming in the middle of an atomic read operation. That is, the drive lost its place while reading data, and restarted in some random incorrect location without alerting the kernel. This case is also corrected by Paranoia."""
