Spiderman 2 soundtrack (question)

Rating: Null/10 (26 September 2004)

I don't know if any of you have even heard of the band 'Strings' or not, because it's a Pakistani band, but recently something grabbed my attention when one of their music videos came on TV.
It had Spiderman 2 clips in it. And in the corner they have those credit things so it said:
Band: Strings
Song: Najanay Kyun
OST: Spiderman 2
Dir Marlon Rodrigues (sp?)
So, I thought they used the clips without asking. I checked it out on the internet and found this article:

(Check the first paragraph. Oh and while we're on this topic, that song is one of my FAVORITES)
(If you want more articles, just go to google and type in 'Spiderman 2 Strings' and you'll get more articles)
But, when I checked the soundtrack, it's not on there. And not even any of the soundtrack reviews/reviewers mentioned 'Strings' or 'a foreign-language song'.
This is eating me up. Can someone help me figure this out?
