Favorites!

Can you please create an option so that we can favorite songs and then be able to sort by that. Oftentimes I generate 10 different versions of a song and I lose track of which song it was that I liked the most. Also when I'm working through a couple different songs I have to scroll and just keep replaying to try and figure out which was the right one. I've resulted to adding and coding into the names so it's easier to search for my favorites.
