The fanfiction might incorporate Queen's music as a part of the magical world itself. Perhaps there are magical instruments in the story that can play Queen's music on their own. And the fem Harry Potter is the only one who can understand the magic within those tunes. Like, when she hears 'Bohemian Rhapsody', it unlocks a secret passage or reveals a hidden spell. It could also be that Queen's music is used in wizarding parties or events at Hogwarts, and fem Harry Potter is a big fan who loves to dance to it.
In this fanfiction, Queen's music could be a connection between the Muggle world and the wizarding world. Since Harry Potter has Muggle relatives, the fem Harry Potter might have discovered Queen's music through them. And then she brings it into the wizarding world. For instance, she could introduce Queen to her friends like Hermione and Ron. They might be initially confused but then get really into it. The music could also have a magical effect on the characters, like making them more brave or creative in their magic use.
