This video acts as a rebus device to convey a message through visual representations.

The message reads: I/ NEED/ HELP /[TO] BUILD /UP /TINMAN /SPREAD/ THE WORD /BURN THE WORLD

The code at the end of the video, another reversed Letter to Number cipher, reads: 9121515160 5220 125152 5102 02807012518120 05071091915031 91908002 Transcribed as: THIS MESSAGE BROUGHT TO YOU BY FOOLS

TIN_MIND1's Audio
TIN_MIND1's audio contains no apparent hidden audio message. However, reversed with speed -50% it produces music with an interesting spectrograph signature.

Efforts were made to find the origins of this music, without success.

Stectrogram: Considerations for Potential Solvers
The spectrogram of TIN_MIND1's audio produces, mid-point, a series of waves and lines. It's evident the audio must be put to use somehow to decode this message. Potential solvers should bear in mind the message found on Tinman's Google+ page: A LINK TO THE BODY IS A TRAIL TO THE MIND.

Perhaps this audio has some relationship with TIN_LINK, TIN_BODY or TIN_BODY2?

An clean extract of these "waves" is provided here.

Perhaps, there is some other means of unscrambling this?
