While looking for old Christmas cards to send, I found this 5+ year old birthday card that we bought to give to our neighbour's daughter, but we never ended up doing so (just gave some toys and sweets). When opened it plays a distorted birthday song due to the age, sometimes it doesn't play at all and sometimes it just makes random noises. I'm sorry for recording vertically, it was intentionally meant to be sent to just one friend, who then convinced me it's interesting enough to post online. I tried recording a better video, but most of the time it just makes no noise, plays the melody more clearly, or just makes weird noises without any melody. Hopefully you can flip and edit it to be more reasonable. I have also uploaded this to the "oddlyterrifying" subreddit, but can take it down there if necessary.
