I just did it and it worked! It’s definitely a jumble of music files but it’s all there, every last bit. Thank you, thank you so much. This has been weighing on my mind for so long, there are so many songs I can put back on my offline playlists now that I have them again. You’re the best!
Just a clarification, Trigun Stampede is not a prequel but is an alternate universe re-imagining of the original.
When the producers approached the creator about doing something very different from the source material, the creator mentioned that the first anime adaptation was “really excellent”, and that “anything beyond the original anime is more of a bonus time, so you could pretty much do whatever you want to with it.” They liked the idea of how, for example, there are different versions of Spider-Man in the Spider-Verse (so that the 90s Spider-Man show, Ultimate Spider-Man, etc., would all be very different from each other). This is them doing that for Vash and company.
It’s very different in a lot of ways, you can think of it as an alternate universe from the original. I would strongly recommend first time viewers watch the original anime in its entirety first and then check out Stampede if they’re itching for more of that world in a very different flavor.
