Spotify is now looking to tap its diverse and big userbase to help them “better understand how Spotify listeners interpret music” and give them insight on how to improve the listening experience. You can now suggest edits to metadata just by clicking the three dots next to any song, album, or artist when you're using the desktop app. Aside from describing music by genre or era, this new Line-In feature will let you describe things differently. But before that it will require you to answer a slew of surveys to test your music knowledge as well as describe the music you like. The edits you make will be considered as suggestions and will pass through different reviews and checks for accuracy before it is shared to other users.
