Multi-Masking

Hey. How you doing?
 If you haven't figured out the lyrics to the song yet:
 1: It's a mouse and a printer.
 The 2nd verse is the keyboard.
 The 1st is a monitor.
 Hang on a second...
 I'm talking like this because it sounds really scary backwards.
 I just hope I don't mess up my throat.
 Anyways, verse 3 is a hard drive and a floppy disk.
 The 4th verse is a motherboard with integrated circuits.
 The 2nd is a scanner.
 I'll see you later. Bye!
 It's a tale that's leading the chase
 A creature stirring blind
 Selected choices locked in place
 and yet another to find
 Running scared, caught in the lights
 with nothing left to waste
 Bleeding black and blue on whites
 repeatedly replaced
 Digits flying in the pouring rain
 A brick wall collapse
 The order left to explain
 The convenience... perhaps
 Arrange in any form or shape
 to carry out commands
 He's got the keys, no need to escape
 Control is in his hands
 I gazed amazed at the TV set
 Assembled dots appeared
 In contrast, a silhouette
 The resolution was clear
 After dark, machines in flight
 on display to view
 The scheme didn't seem too bright
 Pitch black to baby blue
 Reading, writing the arithmetic
 by retrieving heads
 Tables turn as needles prick
 into spinning threads
 A face as pale as a ghost
 The information burned
 And if caught, it would be toast
 and could not be returned
 Racing at the speed of light
 Prepared for the pack
 Unaware of the invader's plight
 all veiled in black
 They crept onto the open field
 the array so precise
 The swarm charged, forced to yield
 then got stuck in the ice
 I'd screen the scene
 and analyze in a single pass
 then translate and plagiarize
 the writing on the glass
 A pretty face taken from a mag
 The headlines from yesterday
 To modify could be a drag
 to connect, plug and pray
