Nah, I don't wanna go through the hassle of putting in real songs only for people to complain about copyrights and other things.
Even though I had permission from the labels to use them. Usually they'd say "Sure, use this one song only" or "If you use this one song, please put this one in it too to promote this other band. That's all we ask." So I did :p
Live and let live. That's what it's all about.
