New compare / streaming history feature: Did user X listen to song/artist Y?

Currently you can only find matching/common songs or artists with another user if they appear in their Top 250 in a certain range as well. But what if I want check if the user has listened to a specific song/artist that doesn't appear in any top list? If you're a friend you could go to the friends leaderboard but wouldn't it be easier to make more use of the streaming history function by allowing the users to 1. search in your own streaming history 2. search in streaming histories by other users (if enabled by the other user) and see you have a certain song/artist in common with them in each other's histories. Ideally generate a shareable image you can directly send to the user if a matching track/artist was found.
