I respectfully disagree there - Uematsu's OST for version 1.0 was somewhat of a mixed bag - for every amazing track (Navigator's Glory, On Windy Meadows, Piece of Mind, The Forest's Pulse, Primal Judgement, Tempest), there were plenty more mediocre tracks that was just indulging in soft metal guitars with little melody (Nail of the Heavens, Quicksand). Of course this is all subjective so what may be rubbish to one player is gold to another.

And Soken has proven he is capable of composing some amazing tracks (The Navigator's Veil, The Emperor's Wont, Penitus, Ultima, Rise of the White Raven/Bite of the Black Wolf) - his only failing was his early experimentation in trying to make music less 'backing leitmotifs' and more just 'ambient sound you barely know is there', something he has clearly taking steps to address due to player feedback.

Having said that though, there's still a few 1.0 tracks I'd love to see return to ARR, but I don't think we need a 'replace ARR's OST with 1.0's option' - it wouldn't even be possible given the far greater amount of content in the game requiring new music which didn't even exist in 1.0.
