So they kept most of the temp music in the film. On the Spidey 2 score album you can hear some of the original material Elfman wrote before Raimi and the TPTB rejected it. Someone on YT posted the original music (by Elfman) from #2 to their original scenes 4 years ago. It's still up there.
You can also find the original music from #2 and (some of) #3 posted on YT somewhere.
Yeah, I know that it wasn't Elfman's decision for his own score to get re-used. A lot of his original score fits really nicely, and I wish a lot of it had been in the film. But other parts of it, like Young's score for the train sequence, are way better than what Elfman had written.
