I mean, I haven’t yet seen a recommendation for a second person to provide accompaniment, but at least here in the US, CPR training does actually suggest performing chest compressions to the beat of Stayin’ Alive

(Another One Bites the Dust also works well, but is… less advised to sing that one while doing cpr lol)

ETA: Just remembered a hospital actually maintains a Spotify playlist of 100 BPM songs to do CPR to: https://open.spotify.com/playlist/7oJx24EcRU7fIVoTdqKscK
