I'm torn. CD-era releases I'm okay with owning only on CD, e.g., Ride, Pixies, Nirvana, even Sonic Youth, to an extent, although I have replaced many of those things with an LP copy over the years. I am adamant about owning vinyl only for anything pre-1987 or so, anything that more than likely was issued originally on LP or intended only for LP-issue.

No kidding. No spam!

^ the big change in the early 90s, that was very important in the rise of 'multi-artist' cd compilations was the arrival of audio software ( OSC's Deck and Sound Tools Session ) that didn't require expensive external hardware to produce a 'Red Book standard' cd master file.
Before '91 the cost of producing a cd master at a pro studio was about £1000 per hour ( with 'industry standard' being 60 mins of audio required about 4 hours of 'work' so about £4000 per cd was considered a good price ).
After '91 lots of small start-ups began offering cd mastering options for £500 for the whole a cd.

When it came to individual artist compilations the arrival as a concept of 'The Best of...' albums offering 'x number' of new tracks alongside past hits, over the classic 'Greatest Hits' albums of an artists past singles, was a major 'sea change' at all the major labels ( and a major boon for the artist as unlike 'greatest hits comps' they counted towards their publishing and recording deals so $$$$$ all round).

Music doesn't appear to be at the forefront popular culture anymore that certainly wasnt the case until id say up to about 5 years ago
