I'm trying to use "tempo" parameter for audio tracks by Spotify API.
I found that following web API (Get Audio Features for a Track) can return "tempo" data which I want.
https://developer.spotify.com/web-api/get-audio-features/
However, it requires OAuth process. Does it mean the user who uses my software to get tempo data must have Spotify account and login ? Is there any other ways to get track tempo data without Spotify account ?
