Hold on I think I got it! The "thing" added to the LPCatalog image resembles to me a spray paint can, like the top of the can. What´s the image on the cover of the "Somewhere I Belong" single? Spray paint cans! And the new voicemail talks about "Somewhere I Belong"! 🤯
If we continue this line of thought, tomorrow they will add to the image something from "Faint" since it was the second single!
