Gave this a listen recently, and I'm not digging it as much as I thought I would. Someone from Neogaf made a post that perfectly encapsulates my own thoughts on the new remaster:
"A lot of the new instrumentation trades the unique, evocative pure artifice of the PS2 sound set for a more literal, but now generically synthetic sound, which makes some of the tracks sound like limp, plastic mock-ups.
Live recording, and higher fidelity synthesis, isn't inherently superior to whatever came before. It all depends on what the particular piece demands, whether previously electronic parts are translated idiomatically to live performance, and how much the originally created version's textures defined the music's charm and ambiance. A few of the changes here are subtle, and amount to improvements to stereo depth and mix clarity, which is nice, but where instrumentation has actually been changed, I'm finding the results pretty rough."
It's downright criminal what they did to "Enemy Attack."
