Spotify has a lot of metadata. It'd be nice to view them to some degree.

Example:

GET https://api.spotify.com/v1/audio-features

What would a user want to do with these primarily?
I think spotify uses these to recommend tracks, so will that be the main use? Find other tracks with similar metrics?

@zrthxn yes recommending tracks and finding similar tracks like done on (everynoise.com) is that I thought of.

I have a local branch with knobs for some of the recommendation parameters, more work is needed, though.

@jpochyla could you create a remote branch for this? I'd like to try to build something for this, maybe something like "tracks similar to..." or playlists of a similar type

Similar tracks have been in master for a while (right click on track). I've pushed preliminary support for the parameter knobs in a0ae674462. I'm leaving this open, as some of the parameters don't have any knob yet, and we might also want to visualise audio properties of existing tracks.
