You both speak the truth.
What really stuck out, Doug, was when you said that you like getting some complete scores so you can make an album out of them. I thought I was the only one obsessive enough to do that!

I love being able to explore everything the score has to offer, and then seeing if I can make a coherent listening experience out of it. I like all the music on FSM's Wrath of Khan release (I really really really do), but the 59-minute program I made out of that is (in my humble opinion) perfect. Another one like this is Alien. The OST arrangement has most of the music I'd want to have on my iPod to listen to whenever - but not all. I included 'Hyper Space' as a bonus track after the main program, because (again, imho) Alien without 'Hyper Sleep' is an unfathomable concept.
As John said, it's great being able to have my cake and eat it too - especially on something like First Blood. Having the whole 45+ minutes (and bonuses!) is fantastic, and I wouldn't get rid of a single second - but the album arrangement went on my iPod, and it's not going anywhere. I still listen to the film version once in a while, but I'm just glad I get to have both.
As for Up... it makes me think of the Varese Deluxe Editions of the Matrix and Scream. The OSTs were severely lacking, and the complete scores are out there in promo form (yeah yeah, I know, but point is, it's not like Stay Tuned where the music was never available in any form). With that in mind, I'm glad Varese created a happy medium - putting on enough music to be satisfying while still creating an album out of it. And again, the rest of the music's out there, so there's no grounds for bitching about missing a 15-second cue. It's a lost art, and I wish it would happen more often. Mars Attacks is another one - whatever the LLL release doesn't have, you can get from the isolated score, so no bellyaching!

So it is with Up - while the promo's contents are nice indeed, the program Giacchino assembled covers most of the bases while being a satisfying listen, so I can't say I feel gipped by it. The hamsters did good on this one.
Keep on doing what you're doing Intrada, coz it's working!
