Wow is a relatively slow form of flutter (pitch variation) that can affect gramophone records and tape recorders. For both, the collective expression wow and flutter, or sometimes flutter and wow, is commonly used.
lyrics
I bent my head to the stream and I fed
a feast of electric blue light
my consciousness is mine to remix
and tune however I like
flashing on, sine wave of the time
grab me some cloud when I want to sit down
to ease the ache of body and mind
aint nobody's business how you get your kicks
no one can walk in the shoes you drive
stepping hard, big and bright
flutter and wow, here and now
phase shift of the infinite ride
static and hiss, the rub, the twist
color the tape as it winds
over and on, wound up tight
