Listed as Stop1 on soundboards, this short button takes its name from Can't Stop The Feeling, the 2016 Justin Timberlake song written for the animated film Trolls, which became a staple of school discos and dance breaks. The stop version is shared among teachers as a practical classroom game sound rather than as a music excerpt. Its appeal is timing: a single tap marks the moment to freeze during songs, speaking games and movement breaks, so it keeps circulating in lesson resources and quick reaction edits.
