It's a shame you can no longer upload music to the InfiniteJukebox. Apparently it relied on a Spotify API that was shut down October 1st. Best hope going forward is an open source library that can offer the same track analysis that used to be provided by that API.

The API was an Echo Nest API. Spotify acquired Echo Nest and shut down all their APIs in 2016.

I'd love to see the app live on too! Spotify's API has similar functionality[1] to the old Echo Nest API, for now at least. (But I don't know if it returns all the same data.) Or, if you don't want to rely on Spotify, I bet Essentia[2][3] could do the job just as well. Essentia is the open-source brains behind AcousticBrainz[4]. So you could either use Essentia directly, or grab the data from the AcousticBrainz API.
