10 Mind-Blowing Secrets Hidden In Famous Songs

6. Linkin Park - Announcement Service Public

If you really, really want people to hear your super secret backwards hidden message on a song, it’s probably a good idea to give them a pretty massive clue about it being there. And so, with all the subtlety of a house brick being put through your front window, that’s what Linkin Park did by naming this EP opener, Announcement Service Public, backwards, get it?

The alt-rock legends aren’t dishing out anything sinister or spooky here though, just some really important pointers on personal hygiene. Stick the track in reverse and you can here, clear as a whistle, Chester Bennington imploring you to brush your teeth and wash your hands, like if Barney the Dinosaur went all nu-metal.

It’s extremely bizarre, but you know what they say - rock cleanliness is next to rock godliness.
