Always believed that we already have all those early albums etc on the random/old tunes.
Artists, repurpose, rename and edit recordings all the time so even if titles and track length differ, we essentially have all those tracks already.
They will have loads of unreleased stuff, unfinished, sketches etc etc but we'll never see those, no one else will do what Aphex did on soundcloud (Mike P did some but... whatever). All those hundreds and hundreds of finished unreleased bangers ended up being an underwhelming bunch of sketches. Of course that dump is strewn with little gems, and potential but honestly, we only hear the best of any artist because that's the stuff they care about the most, enough to finish to the point they are proud to let people hear.
You could feel the bullshit
