I personally like the audio changes. In fact, despite criticism from some, I like to default music list too. It reminds me of a more modern version of the soundtrack for older titles like 2097 or Wip3out. There are a lot of new faces that don't remember the older music, but I think it is a modern take on the older games. Meanwhile. the new sound effects seem updated and I actually like the new rocket noises. It sounds more like a "rocket" should sound.

Think of it like this... the 2048 chapter has different sounds than WOHD. Would you want the sound effects to be different for just that game? I personally like that they have new sounds across the board. It gives the various titles a new more cohesive sound.
