F# major · 83 BPM · 59.3s · I – vi – ii – Vmp3
A 59.3-second F# major song at 83 BPM. Its score spells r-o-l-l-i-s-u-p, one note per letter, and the card and video show those notes. Written by SoundChain's anthem composer from the name alone: the same name and composer version always give the same song, and a claimed anthem never changes.

The proof is the sha256 of the score: its version, names, tempo, key and every note.
