Not everything has to be a "limited edition super deluxe box set". That's emphasizing quantity over quality. I'd rather forget the filler and have the best possible sound quality (ie Dolby Atmos, multichannel, high bitrate). I'm not interested in having a photocopy of a ticket to a concert I didn't attend, and I'm not interested in having a postcard or a ribbon or a guitar pick or a magazine cover or a piece of chalk. That's just gimmicky nonsense.
Not only that, but putting things in a boxset like that means I'm far less likely actually to play any of the discs. Example: Nirvana's eagerly-anticipated boxset - I've got a copy, but it's never been in my car, etc. it's stuck on a shelf, separate from all my other music (because it doesn't fit), and I kinda forget about it.
Oh, and that price, lol.
Another Nirvana example - the recent anniversaries of both Nevermind and In Utero, both came with 4 full concerts on CD/DVD. But the price was so high, and the numbers were so limited that I couldn't get a copy in my local store. If they'd sold each concert separately, at the going rate (ie $15 each), and actually made them available, I would happily have added them to my collection, but alas, they lost the sale.
Same thing with releases from REM and Beatles and GNR. If you're not gonna properly release something, why create it in the first place?
