[Desktop][Discover] Favorite Song Feature

[Abysu]

I think there should be a feature where you can choose a favorite song. The point of this feature is to show the algorithm for finding music you like (such as Discover Weekly) what kind of music you are really looking for at the time. This will be especially useful for people that have many genres in their liked songs because instead of having suggestions from that entire list, it will narrow the suggestions down to the genres of your favorite song. For example: I have a lot of rap in my liked songs but lately I've been getting into alternative rock and I'm not a big fan of rap anymore. I wouldn't want to be suggested rap anymore so I would choose an alternative rock song I really liked and favorite it.  Now, the algorithm sees that I want to listen to alternative rock instead of rap, so it starts suggesting that instead.
