问题
I am trying to build an application that plays Spotify songs. I am really confused about how to change BPM(Beats Per Minute,) value of Spotify songs.
First Step: Login through Spotify.
Second Step: Get Current user all album.
Third Step: get album track.
Last Step: play track.
I have done All step with Spotify Delegates. but I want to change the BPM value of the track.
Can someone please explain to me how to change the BPM value?
