Thanks, MusicMachinery.com (and we mean that both sincerely and facetiously) for turning us on to the mesmerizing Letsdance.to, made using The Echo Nest API.
The site takes various dance videos (some hilariously dated) posted to YouTube and syncs them with hundreds of BPM-analyzed music files, to create surreal visual/audio experiences… like Fred & Ginger fast-dancing to Radiohead. Or these guys dancing to The Hives’ “Walk Idiot Walk.”
Check out the most awesome thing you’ll see today at Letsdance.to. You can “thank” us later.
