Well, I'll admit the choice of new music is funny, but you can't just throw copyrighted sound into your pack willy-nilly, so you'll have to take it out... unless you've somehow gotten explicit permission from the creators...
I added a lot of sound changes in the update i am making now. it will be up any minute
It's illegal to put sounds/songs you don't own in you're pack.
And I think you should make some textures that are original and made by YOU before you add sounds that aren't yours. (Not that you should add songs you don't own.)
