Ravel's Boléro, the famous repetitive piece that builds to a full-orchestra climax, is the most famous example of a classical form, based on the Latin dance genre of the same name. TV Tropes, a website made entirely of rabbit holes, lists over 50 examples of this particular song structure, and we've collected as many as we can in a Spotify playlist.

The bolero is a catchy, hypnotic structure, and we've found it useful for pushing you forward as you work on a project, the music urging you toward your goal. We hope it helps you get things done.
