Joining the Jam

So I guess as an introduction, I'm a 3D artist and this is my first ever jam (so excited! :insertpartyparrotemojihere:)

For this jam I will be using: 3DS Max and Photoshp for Graphics Unity 3D for engine Code? I can code :( , so I will be using Playmaker instead :yay: Music and audio, not sure how will I doing this. Can I use any royalty free music tho... :thinking:

Can somebody advice me on the audio part...
