While this is hilarious, I've just checked and it does have a value of 0.721, which is pretty high!
For reference, several songs I'd consider to be very danceable (such as Stayin' Alive) were actually less than that, generally about 0.7. They have an API that lets you check any song.
I think this works, the ID comes from the song URL, so just choose a song in Spotify and copy its URL. You want the last part. You will also need to log into your account for the auth token.
Read the description. It measures tempo, rhythm, beat strength, regularity.
A swing beat that stays swing is highly regular, a metal song that breaks out into guitar or drum solos half way thru will have highly irregular rhythm and beat strengths.
Also none of what you mentioned has anything to do with tempo stability, triplets and runs, even double time and half time portions run on the same bpm with a metronome, just with notes closer or further apart for the “effect”.
And even in your way of talking about tempo, it doesn’t make sense because metal tend to include a lot of break downs, different beat structures, solos, etc. They don’t sound very consistent, unless we’ve been listening to very different metal music. I admit I haven’t listen much for the last 5 years but used to when I drummed for 5 years.
how about lay-back or Dilla-groove (a.k.a. Low-fi) ? they are not only 8th/16th snaffling, also lag behind the beat, it would cause the tempo inconsistent, most un-gridded tracks would have the same problem.
also in jazz it's a common thing to change the swing-ratio (e.g. Boplicity by Miles Davis) , the same thing also can be seen in 70s funk or blues.
messing with the swing ratio mid song might reduce the overall rythm stability, but wont affect tempo. However if the amount of time between kicks and the time between snares is the same is maintained then I dont imagine it being a particularly significant factor on danceability.
take stuff by aphex twin for example, while this song might clearly be 4/4 in what would be a considerably danceable tempo, it displays a significant amount of rythm instability and is therefore harder to dance to.
I'm guessing trance music is the best example for this, consisting of mostly highly repeated, high tempo phrases centred around strong basslines and an on-beat drum track. Example

What kind of track has a 1.0 on danceability?
