Is information about tempo/bpm actually correct?

Issue found on May 1st, 2020

Endpoint(s):

• GET /v1/audio-features/5A32KQZznC2HSqr9qzTl2N

Scope(s):

• playlist-read-private

Steps to reproduce:

1. Open the API Console
2. Call the audio-features endpoint with track_id 5A32KQZznC2HSqr9qzTl2N

Expected behaviour:

Correct tempo is about 160

Actual behaviour:

Tempo returned is 85

I used the API to categorise some songs by BPM but I think 90% out of 140 songs I processed seem to have incorrect bpm. Either all songs are around 95 or some slower songs suddenly get 190-200BPM
