Stereo Tremolo

Is it possible we are just programmed(?) to interpret certain signals and call it reality?

life's the same i'm moving in stereo
life's the same except for my shoes
life's the same you're shaking like tremolo
life's the same it's all inside you
-The Cars

Invisible airwaves crackle with life
Bright antennae bristle with the energy
Emotional feedback on timeless wavelength
Bearing a gift beyond price, almost free
-Neil Peart

If you hear the song we sing
You will understand.
You hold the key to love and fear
In your trembling hand.
Just one key unlocks them both
It's there at your command
-The Youngbloods
