A lot of artists especially in the rap/electronic genres seem to be signaling either that they're ascended/approaching ascension and/or nearing the ends of their journeys or 'mortal' lives, and I think examples with the weekend is that he's withered/old having lived his life. I don't know if they think they're going to die soon or if they think they're going to become something else.

the other photos I see a lot in rap and I think that is in part due to idol warship being a big thing in the rap genre, and in an attempt to 'immortalize' themselves they will display busts that typically were only reserved for great works of art, depicting ancient gods, or emperors. It all seems like one big ego flex to me, and I won't go so far as to say its anything evil (I have no idea), but the music industry is pretty sketch and into a lot of weird esoteric stuff and 'ceremonial sacrifice', 'death', 'rebirth'.

I honestly think a lot of them view themselves as Jesus/godlike or part of a new royal class and their lyrics and imagery really seem to at least hint at that as well.

I think, just like everybody else, they feel something is coming, and they want to be a part of it, while doing absolutely no work or real life changes to that end.
