🎶 PID control loops are just great
But I can fit in less than half the gates
They got so little of that overshoot
But I don't need expensive analog, oh

You've been waiting for that
Step on up, write your code
See, PID loops would get the job done
You need a cheap way to keep phase lock, yeah

Bang-bang CDR locked (I know you want it)
Bang-bang cheap control loop (I'll let you have it)
Just wait a minute, let me lock your phase (ah)
And wait a minute 'til you (link, up!)

(I really need to finish the lyrics for this one then find someone to perform it...)
