It'll be harder to find a website with the tunes, as WWE seems to look down on the distribution of their music. The couple of times I've looked for a theme I've run into a lot of broken links and pages removed.
I used the dreaded Kazaa and found it very easily that way... I can prolly find it again (Seeing as how I made a CD and deleted it)
The song is called "Across The Nation" and it's by Union Underground
That info is from the sleevenotes of Forceable Entry (Which I have the case for but the cd disappeared)
CHARLIE: I should have gone in. I'm such a chicken. I should have kissed her. I should go knock on her door and just kiss her. It would be romantic. It would be something we'd tell our kids about someday. I'm going to do that right now. (Drives Away)
Well you can right click on a song in iTunes and convert it to another format. Have to go into options first and set it to import songs in whatever format you wish to convert to, like MP3. Also QTFairuse is handy sometimes. :)
