You could map each quantifier to a drum hit, but a greedy `.*` is a bass that swells forever—just wait for the catastrophic backtracking to drop the whole track. Use a non‑greedy `.*?` or a lookahead so the beat only hits when it has to. Recursion is like a looping hook, but if you forget the base case, the track will spin into an infinite loop that never hits the chorus. In short, treat regex as a MIDI sequencer, but make sure your pattern doesn’t throw a stack overflow. I prefer debugging old code to listening to glitchy beats, but a well‑structured pattern can still make a decent loop.
