I tried using the search function, but I couldn't find the answer, so...
What are the laws regarding placing commercial/licensed/copyrighted music/songs in flash movies on newgrounds.com or any website?
For instance: If I use Interpol - "The Heinrich Maneuver" as a background sound in a flash game, would I get in legal trouble? I've seen flashes use copyrighted music before...
Your response(s) are greatly appreciated - thanks!
