This week's song is Worlds Apart by Twenty Twenty.
I picked it because it is Tristan's and Dulcie's couple theme tune. It's their theme tune because it fits the whole thing of how they are different - Tristan is human, Dulcie is fae - and yet, no matter what, even though they've been through so much crap, they will be there for each other. Because they love each so much. Though it does take them a long time to realise that, but never mind.
