I've done the same. You can get some obscure stuff from soulseek if Lidarr isn't finding all the stuff you want. I'm mostly using that and just using Lidarr for organizing and tracking.
You're 100% right about the plexamp DJs. They're super good. Love the deepcuts one.
In the book there are some references to Rita (Emily Blunt) fighting in various places and I think her getting her start in South America. Might be remembering that one wrong, but a prequel with her learning how to fight the monsters would have been good if they stuck more to the book.
You've listened to the Pete Seeger song though right? Solidarity Forever is based on The Battle Hymn of the Republic. They both use an AAAB rhyming scheme and I think are in iambic octameter but I'm not a professional. Pete Seeger didn't write it, but I love his rendition. He's got alot of great labor songs.
