Favorites Section/Song Reviews

I'd really like to have an option for our profiles to have a favorites, or maybe recommendations section. Like, an area where we can put songs that we think are worth hearing and a way to caption each song with what we think is special about it, you know? I feel a bit gauche referencing another app while making a suggestion to the devs, but the first thing that comes to mind for me is Letterboxd. Not a very articulate idea, but hopefully I make sense.
