Digital glue

If I'm just laying a track that wraps around
Different ones 'til it comes back, creating sound
I'll send it up six hundred miles over the ground

So everyone gets the waves I made for you
Stuck together in a digital glue
Envelopes fade out the useless
But you don't have a clue

Anyone meaning to try on their own
Should have a steady supply of semitones
And if they should find it ain't easy
I've worked to the bone

People want to hear the harmonies in clear stereo sound
But first I gotta drink, my mind won't let me think now
The melody rises and falls to the ground
