The entrance of Weyes Blood on the title track during that last chorus as the aforementioned “sweet angel”…a top musical moment of the 2010s, in my opinion.
Yeah, i didn't know that either, only saw that I lot of people were comparing the two around the time of release.
I'm trying to find the source, but...I dont think he co-wrote the song directly perse. It was more they were talking and he gave him some song-writing tips on that one. I think it was in an interview somewhere back around the time Bo's special came out. This is proving hard to find now though, so forgive me if this info is incorrect, my apologies.
