Extracting audio features from a custom track

[ludwikbukowski]

Due to The Echo Nest's Important API Announcement, March 29th 2016[1] their platform will no longer serve requests and developers will have to move over to the Spotify API. However, The Echo Nest has been providing a quite important feature which was the extraction audio features from a custom uploaded track.
Will it be also posible to obtain those features (like danceability, energy etc) from audio file after the migration?
