Late to the party to read, listen and comment, but this post was open the whole time since I first saw it a few months ago.
I am not someone who knows about details of music, cords and whatnot, but I do know what I like.
Some of the songs I find too commercial for me, to similar, though yea, I know, similar-sounding songs to whatever is out and about, still can be quite different in 'quality'. I do very much like Sienna. What a voice she has, WOW! The Armenian as well as the Scottish 'boy' band, I will dig into more, also very interesting. Molas, I also like. Listed to check out more of her/their works.

Missing much in your list, though. The ones that came to mind when writing this sentence (they are just two random songs/artists that are high in my large list): Nils Frahm (almost anything from his hands), Roisin Murphy - Ancora Tu, Massive Attack (almost anything from their hands), Talk Talk and specifically their last two albums (Spirit of Eden and Laughing Stock. Owww my list goes on and on. Mostly with not so much pop songs, but better 😉
