> On repeat: Make an extended version of your song's favorite part by choosing the catchy part and seamlessly repeating part of it!
John Mulaney's "Best Meal I Ever Had" story[1] had me wanting to do this for Tom Jones' What's New Pussycat so I could play that as an inside joke with some friends. This would definitely have made that easier. (Ultimately, I had a version of the song which started in the middle and "ended" right before it "started" so the effect could be mimicked if the file was played on loop. This had a short silence manifest as the media player "loaded a new song" from its perspective; didn't have that issue in Audacity.)
