What are the terms of use for songs on newgrounds?

I'm currently in the early stages of making a game for the iPhone and android market and i was wondering if music on Newgrounds could be used in it. If no are there any sites with music that can be used for these purposes? If no again are there any programs for a beginners such as myself that I could use to create my own music for this game?
(Note: this game will be sold for profit)

  • Would this be against Instagram terms and conditions? I have OCD and created multiple accounts on Instagram with multiple disposable email addresses, not knowing that there's a limit in how many Instagram accounts you can create per IP address. I only have one iPhone. Would it be against Instagram terms and conditions to have Apple give me a new IP address on my iPhone so I can create one more Instagram account that I can use permanently?
  • Why do they keep asking to agree the terms & conditons? In the app store on my iphone i'm trying to install the tumblr app and this pop up asks to agree to the terms & conditions and I have like a billion times but it still won't allow me to download the app without agreeing to the terms and it's really annoying
  • Itunes Terms and conditions? I Just Got A Iphone 5 and i put my icloud and everything and i want to get an app and it says "before you can process you must read and accept the terms and conditions" And i don't know what to do
  • ITunes annoying 58 page terms and conditions? I can't download free apps or buy new lives on candy crush on my iphone because when I try it comes up saying the iTunes terms and conditions have changed and I have to accept them or something. There's a link saying 'send to my email' which doesn't work, and when I manually click through All 58 PAGES and get to the end there's NOWHERE to accept ANYTHING.
