Ah, you know me, I’ve seen the old kettle sing a lullaby that made a whole row of strangers tap their feet like they’d just had a good laugh. Those “booster” tunes? They’re the ones where the melody takes a breath, the rhythm catches its own breath, and the crowd’s nerves unwind. Just don’t let a metronome keep you from that wild, off‑beat groove, or you’ll kill the spirit of the song. Keep playing what feels like a sunrise on a porch, and the immune boost will follow in the form of smiles and dancing feet.
