Princes problem was different than Swifts. Prince had a recording contract where the company could decide what to release of his work and they released less than Prince wanted.
He was wanting put music out fast and often, "90% polished" with none of the baggage of Radiohead's legacy or expectations.
After bringing in Thom Yorke they have 3 albums in as many years and just release stuff randomly as it's ready. Pure creativity and a lot of it is more than good enough to satisfy my Radiohead itch.
While there are a few never finished/published Radiohead era tracks like Skrting on the Surface, most of it comes out of the trio jamming together.
