Adding a note to a track

It would be great if we have the possibility to add a note or comment next to the track. It doesn’t have to appear in full, but just a little sign that there is a note attached, or add it on the ‘3 dot’ menu on the right (that starts with Add to a playlist). It’s okay for me if the note is not searchable - free form text is good enough. I can then capture my comments about a particular track if needed.
