Thanks for the update, interesting to hear the changes, you seem to be the first to notice! I'm glad to hear (pardon the pun) they're making improvements still, music and sounds really complete any area in a theme park and it had been lacking in Thorpe until last year. Although it does surprise me that Saw and Swarm was done, I hadn't noticed any broken speakers in those areas (if anything Saw was louder than before in recent years). Glad to hear they've kept Hello Zepp though, really love that soundtrack, and it's very synonymous with Saw.
I wonder if Inferno's old soundtrack returning is going to be short lived like Colossus's was a few years ago...
