[Minor feature] Annual listening statistics

[ChibyX]

Now is year's end and different music streamings show you your top songs, artists and other stats for the past year. It would be cool to have something like that in NC music. No, I don't ask for colorful presentations. But this app is already collects some statistics (because I can see "top albums" in my Subsonic and Ampache clients and it's definitely server-side data) and there's could be an option to get it in text and numbers.

Thanks for the suggestion.

What we currently store, is the total play count per song and the latest play time of each song. This is not enough to create any yearly stats as we can't separate plays of the earlier years from those of the latest year. To be able to calculate the yearly plays, we would need to additionally store a snapshot of the cumulative play counts at the end of each year.

This feature request has also some synergies with #1189. If the statistics were offered through a suitable API, then the Analytics app could be used to visualize it either as table or a graph (although fancy visualization was specifically not required here).
