I don't get the whole "mood music" type argument. I feel like any type of song could be based on mood. I can go from a FKA Twigs song to a Katy Perry song without "mood" interfering.
Well, I don't think they mean when you're sitting at home being pretty neutral and like listening to whatever you want.
Like if you get drunk as **** and wanna dance and have fun and basically have a wild night out, would you want to listen to Lana's songs?
