I've sent an email, should give you access to a new project I've set up for licensed versions of the music. It should give you a free copy. The project contains MP3 and WAV formats of the songs. Download these ones and use them for your Christmas game, a credit would be nice but not required. If there are any issues email me back.
Thank you .. and yes I will leave credits !! Thank you very much, it helped me a lot !!<3
No worries, it just surprised me that someone wanted to potentially use it so I wanted some time to think about it plus took about 2 hours to set up the page XD Let me know about your game when it's done!
