The Metallica remasters were all over-compressed messes, so I guess it's really whether you're in the camp of "I just want bonus material" or "I just want the best possible sounding version of that album" and sadly, rarely do the two meet.
Exceptions to the rule would be anything Steven Wilson is involved in. Look at XTC's 1979 release Drums and Wires (everybody probably knows the song "Making Plans For Nigel") - the single Blu-ray has 117 tracks all beautifully mastered:
New stereo mix = 12 tracks
Original stereo mix = 12 tracks
Instrumental mixes = 12 tracks
5.1 mix = 12 tracks
Bonus tracks new stereo mixes = 11 tracks
Bonus tracks 5.1 = 11 tracks
Demo session 1 = 6 tracks
Demo session 2 = 4 tracks
Demo session 3 = 4 tracks
Demo session 4 = 4 tracks
Rehearsal tape = 20 tracks
DJM re-recordings = 3 tracks
Various original alternate mixes = 4 tracks
Promo videos = 2 track
AND, it's only US$22 -
