I personally love every Ticket to Ride variation as well, but especially Rusty. It's such a jam (and I wasn't forced to listen to it for hours trying to solve some puzzle in a train car full of assholes). Another one of my favorites is Table for Tooth, which is the song featured in Hiveswap Act 1's trailer. It's so energetic! Any of the "battle" music in Hiveswap is a banger in my opinion. But my absolute favorite is definitely Homestead from Act 2 (the song that plays inside Zebede's hive). It's not super bombastic or iconic like some other tracks, but it feels so warm and homey. I listen to it all the time when I want to feel calm and cozy, like when I have a cup of tea or read a book in the evening.
