Spotify is calling on its subscribers to help them identify genres, moods and aliases.

To help, the Swedish streaming giant has today quietly unveiled Line-In, a new tool which it hopes will it add more precise metadata to its vast library of music.

Once signed up, users will be greeted by a series of surveys which will help the streaming giant distinguish between artist aliases, track genres and moods.

Spotify has reassured users and artists that all suggestions will be vetted and then ranked based on the quality of past submissions.

“Listeners describe music in different ways, and understanding that information will help improve, extend, and confirm the information that describes music on Spotify,” a spokesperson recently told Variety. “We hope to better understand how Spotify listeners interpret music, so that we can improve experiences for both listeners and artists.”

In other Spotify news, the streaming giant has begun testing a new auto-mixing feature where AI will help mix music automatically within playlists.
