Loathed fade-outs seem to be a big issue in the Genesis fan community
I see that it seems they were too lazy or unable to write a 'proper' ending. And there ARE some great proper endings in the Genesis & Co. catalogue. On the other hand a fade-out may be intended as such by the composer(s). Some composers of the past writing 'perpetuum mobile' pieces for piano might have been happy, had it been possible for them to conclude their pieces with fade-outs ...
Of course I don't like it either when tracks fade out too chokingly quickly. Then I look out for a live version or alternative mix ... What I do prefer to fade-outs AND proper endings ist seguing pieces, anyway (as on side 1 of Smallcreep's Day e. g.).
