This comparison of songs between Billy Joel’s Greatest Hits Vol1 and the original tracks has an interesting issue. Each track on the greatest hits album has been cut by at least 3 seconds or more, and in one case, almost a minute. You can see divergences in the track boundary lines.
Fortunately, you can still make decent sense of the matched up waveforms and it’s pretty obvious that not a lot of reprocessing was done on the tracks.
