my copy of the lp arrived today and I noticed that on the all four sides there's a message very lightly cut into the inner ring.

On side B2 there's an address for a youtube video which looks like
youtube.com/watch?v=lFd0hztEUW9

which leads to an 'unavailable video'
some of the characters are pretty ambiguous,the l/1 the 0/O and interestingly the 9 though I have no idea what else that could be. I have tried different combinations and each leads to a page with the same message. I was just wondering if any other vinyl owners had any more luck with the URL?
