Show playlist creation date

[atheisticfront]

Be able to show date playlist was made and date it was last added to. Desktop shows date songs were added to each playlist so the data is clearly there and this is doable. Just 'Created d/m/y' in small text under where it says the playlist length on desktop and mobile.

We would love to see when a playlist is created to remember when a certain music genre/playlist was relevant in our lives.

Many of us associate music to a certain time period of our lives.

An option to make the date private or public would also help people to hide the date from others. 
Thank you:)
