Something I find hilariously ironic about Gone Angels (or how the fandom treats and interprets it)
So, nowadays, Gone Angels has become kind of a meme, a song synonymous with 'wife dead, me sad' and is often associated with Roland and Angelica, and his grief for her.
However, though, if you actually look at Gone Angels' lyrics, you realize... Angelica is barely a part of the song. If anything, Gone Angels isn't a Roland x Angelica song... It's a Roland x ANGELA song.
The lyrics are entirely about Roland's complicated feelings towards her. His volcanic fury and hatred towards her and her actions and attitude, his unspeakable grief and guilt over the lives that they both took within the Library, and how his genuine love and affection for her muddies that fury.
The Angels in the Song aren't meant to be Angelica, they're meant to be the victims of the Library (which, yes, COULD also include Angelica since Roland places the blame for her death squarely on Angela's shoulders, but considering how the Angels are explicitly compared to bookshelves, it's pretty clear that they're indeed meant to be the many, many victims of the Library.)
"So, let me take your hand, like one of those mad-men.
"Tip tappity tappity tap.
"Dance our last dance."
This isn't Roland dancing with Angelica... This is Roland dancing with Angela, sharing one final moment of connection, one filled with so much longing and affection that it borders (or maybe even somersaults through) between being platonic and romantic, right before he takes her head off.
This is even supported by the Phase change. Once Gone Angels kicks in at the Fourth Phase, the battle explicitly goes away from Angelica and focuses more on Roland's actions within the Library, his decks become filled with memories of the many atrocities he committed under Angela's command, and even his background is FILLED with enormous piles of books, all of which were once people of the City.
So, basically, Gone Angels is literally a Rolangela song, through and through, and it's not even the ONLY official Rolangela song btw. String Theocracy and Poems of a Machine are also extremely strongly-coded Rolangela songs (albeit both from Angela's perspective.)
