The band Clannad, and her sister Maire Brennan. I really love Clannad the most, I think. Clannad did all the music for the Robin of Sherwood series back in the 80's (my favorite Robin Hood). Enya sang with them on a few albums before she started her solo career. She did the music for a series "The Celts" and her music was perfect for it, of course.
Here's Clannad:

I only know what filters down to me at my level, years late. Plus, to the inevitable question, "What kind of music do you like?", I go into a catatonic state trying to figure out an answer. The questioners go into a state of puzzlement, like, why is this a hard question!

Well, the answer is, I was in the band, my mother's musical root was Classical. So for the first third of my life music meant Classical. Then I spread out but detached from being a follower of anybody, crossing genres based purely on MELODY (and NOT lyrics).

So, I like *ONE* song from Willie NELSON (actually, 2 or 3), but NOT "country music." I like ONE song from this genre and that genre, but NOT the whole of any genre or any one artist, usually not more than one, two, or three by an artist.

So as for the songs listed in the o.p., when I "discovered" Chandelier, somebody here attempted to explain the painful context of drug and alcohol hell that Sia had gone through as described in the lyrics. None of that penetrated for me. All that mattered was the melodic "hook". I don't care about the story and the video of the girl dancing meant nothing to me and I would never look at such a video again, not 30 seconds.

No, will not add "sorry" here. And in the commercial for Dior, notice that all the psycho-drama of "Chandelier" is omitted and only the soaring hook is left to match the elegance of the perfume's image.

Same goes for the other ones and any other piece of music. As Lenny BERNSTEIN said in one of the Young People's Concerts, the lyrics to any song can be erased and be substituted with any other lyrics of any other song or nonsense words. The words of the Ave Maria can be dumped and have inserted commercial jingles to the sublime music and the music is still there and is ALL THERE IS.

Or as Lord Chesterfield said, "What is too silly to be SAID, is SUNG."


*********But really, thanks for the context of the other songs. You can judge from what I've said whether the song you reference will meet my stipulations. Although, more often than not, an artist with one song of melodic gold can be expected to have more than one, no?
