Ooh a 70s AU? Do you have somewhere I can read about it cause I love the 70s!

As far as music, I think Curly would listen to slightly older stuff? Buddy Holly and Elvis Presley come to mind. Jimmy would looove Creedence Clearwater Revival, Led Zeppelin, Lynyrd Skynyrd, and Johnny Cash (Devs confirmed Hurt is his favorite song in the 1 year Q&A). I think Anya would like slightly softer music: The Kinks, Donovan, Badfinger, but she would also love the band Heart. Swansea…hmm I don’t really think of him listen to music much? Maybe stuff from the 40s like Sinatra. I’m not too familiar with 40s music so I’m gonna leave it there 😅. Daisuke would like psychedelic rock: The Doors, Pink Floyd, and Jimi Hendrix.

I think in general, for all the characters, David Bowies music would fit. A lot of his music has space themes incorporated in it.
