Don't get me wrong, it's one of the best few minutes I've ever seen in a piece of media. But it's a part of the film, and it's too special to just watch 'till you're sick of it. It would be like having the climax of Lord of the Rings on your iPod.
I'm probably the other end of the spectrum to an extreme. There are songs that I won't even listen to because they're used in a favourite movie or show of mine and I want those scenes to be that much more awe-inspiring whenever I watch them in the movie again("Head Over Heels" with Donnie Darko, for example).
