I get that modern software is a living breathing thing, but it's absurd to compare that to music albums, which should not be constantly modified and reissued post-release.
...remasters?
Conversion of tape to plastic to mp....
Newer, better(?), tech available for engineers.
Zappa [iirc] made his plastic lp's 22 minutes a side as that gave the optimum wiggle room for needles, both at the presses and domestically.
Led Zep (ahem) re-released an awful lot of original material.
That's not what I'd define as constantly. And I have no problem with an artist wanting to release their own music this way, but if it were the industry norm I imagine I'd find it insufferable.
