Trent is not part of radiohead; Radiohead and Trent(nine inch nails with ghosts) did the same thing but at different times.
Not exactly the same thing: Ghosts I-IV was fixed price(s), provided lossless downloads, under a very permissive CC license and the first quarter was put on torrent sites directly.
Similar yes, same no.
My comment was mostly just to correct the "Trent Raznor's(sic) Radiohead" part of the op.
