Gold Record?

[Easterwood]

I was exploring in map 1 the other day, and I found this room with signs that say something like this "I have a tale to tell so listen well, in the sea you will find a light, in there a record of gold, bring that back, but not until after completing the challenge, and put it in the music box." (That was probably way off) but I was wondering if it's possible to find the gold disk now since the chests are randomized? I know you could try to get a skeleton to kill a creeper, but mobs are off now. So if anyone has found this or knows anything please let me know!!! I think I found the room, but i didnt go for the challenge because i wasn't sure since the chests were randomized.

Yes, in the normal survival games map there is a light in the ocean that you *might* see eventually.
If you go there, I'm pretty sure there's a chest with a golden record in it (also pretty sure it's '13').
You go back, put the record in, get something special
