Sorry if this has been discussed before, it’s really hard to search for edits (as in when one recording is an edit of another), because the term’s also used for us editing the metadata…
So, one recording can be an edit of another. But what counts as an edit? It makes sense to me that if the original artist took the multitrack files / stems and trimmed the mix down to a shorter version, that’s definitely an edit. But say a mastering engineer needed to fit more songs onto a compilation disc or tape than would fit, and they simply faded a song out halfway through, does that count as an edit?
I guess I’m overthinking where to draw the line… Something like “if both versions of the recording have been released, and are a different length to each other (excluding leading and trailing silence), then it definitely counts as an edit”. But such a description would include DJ mixes, so I guess you might want to exclude other artists’ edits that are part of a continuous mix?
