What's this "albums as intended" bullshit anyway? iTunes store sells full albums, iTunes the player supports full albums happily.
Also, when buying, there's plenty of examples of "Album Exclusive" tracks where you only get certain tracks if you buy the complete album. Even Antiform did that:

Also, if you've purchased a tracks/tracks from an album already, they still offer you full album pricing if you decide you wanna upgrade for the cost of full album price minus what you've already paid for single tracks.
I'm not even touching on the iTunes LP concept either.
Maybe, just maybe, people aren't buying albums these days because the vast majority of pop music is based heavily around singles instead making for shitty albums full of all the same tunes you already bought. The singles are getting released long before the album and people are wanting to buy them then and there. Then, the record company wants to shake you down to buy them all again in album form - don't be fucking stupid, I ALREADY OWN THE SAME FILES. Arguably, iTunes is better positioned to deal with that than anyone else - with the album upgrade I mentioned above. "Hey, you already own 3 singles off this album - for only $X you can upgrade to the full album!"
Look at the way the industry is working before blaming iTunes or listeners first.
