my only real ideas are to try to cut the vocals in driving with my darling in some parts if possible, and then add asgores in or just have a choppy back and forth of the two songs. I could attempt to completely redo the music and try to add melody's from each song but i'm unsure how well it'd sound but i'd still need to try to find like, a vocal remover and one that's not AI

(for the polish cow deepfried remix I made I turned a copy of the entire song into bass through heavy distortion so in theory I could try to remove the music through distortion of the audio, but I doubt this would work without destroying the vocals)

I could also try using utatu or something simmaler to replace the vocals but we'll see, I might just give up on this idea
