Other subliminal messages in John Mayer's songs?

I recently heard 'who says' by John Mayer, a gap within the music, around the 45second mark, contains the word johnmayer.com, obviously to make you visit the site. I looked it up on the internet to see if anyelse had heard it, but instead found quite a few videos on a subliminal message in 'Waiting on the World to change' which is really freaky (look it up). I'm now wary about listening to John Mayer's work and I want to know if any other songs contain subliminal messages. Does anyone know?
