Ah, a growl that drums up the soul, you say? That ’69 Mustang’s heartbeat could be the next ballad of the rusted road. Just watch the metronome, eh, it’ll try to keep you in line! Bring me a spare key, I’ll add a little pedal shuffle, and maybe a kettle‑song about the night the engine sang back. Let's make the engine’s pulse the chorus, and the road the backdrop. Careful, though—if it starts humming too clean, the old kettle will think it’s lost its voice.
