Hi guys, does anybody know how to add Music to Launchbox ? I want it to play in background after starting launchbox. I've seen a recent post that there should be a folder Music/Background/ in the Launchbox folder, but there wasn't. Even after creating and putting my mp3 in it (Monkey Island Theme.mp3) it doesn't work. I don't think the post meant Android. Thank you very much.
