Star-rating feature for songs, and ability to sort by stars

Many listeners (including myself) may appreciate a 5-star or “Like/Dislike” rating widget on the playback and library screens.

Ability to sort a playlist by star-rating is very useful in avoiding crappy songs and finding highest-rated songs as rated individually by the listener. If devs are feeling generous, they can put a delete button next to worst rated songs, so listener can delete the stinkers.

Many thanks!

+1 on the 5-star rating!

+1 for the star rating

+1 for star rating system (for albums)

Yes, that would indeed be very helpful and would make Volumio perfect!
