It would be great to know the year of release of each song (the month would be great too, but one step at a time). When you listen to Spotify's suggestions, or when you listen to any playlist, you might want to find out what year a song was released.

In some cases, you are interested in knowing when a song was released due to the lyrics it contains, in order to be able to contextualize it in a specific historical period.

It could be good for all users who like to sort playlists based on the publication date of individual songs.

I love music from different periods and I dream of being able to read the release year of each song in every context (web, desktop app, mobile app, smartwatch) to better understand its essence. Why did they use those words? Has that particular sound been made by anyone else before?

It could be an option to select: each user can choose if he is interested in having this info or not. It could be in a new column of information, or directly in the title.
