I have had tried multiple discs and they disappear after spamming putting them in and out. after 3 times, the music Discs will disappear while inside the jukebox. and do not come out. I can put another inside kinda like my Toyota Camry with a 6-CD Changer but not as cool. even when broken it does not reveal any discs. 

ps. The Jukebox is not near any Hoppers
