I couldn't agree more! Also, over at OC Remix.org you can download a totally free remix album of Nights: Lucid Dreams in honor of the 15th Anniversary!
Yet reflecting back, I wish Sonic Team would have carried on the series instead of quickly freezing it and using it as a hardware experiment. I remember when "NIGHTS Score Attack" came out on the GBA and thought there was going to be a real game. The Wii edition I won't even mention since I feel that was a bit of an odd twist on the series and I feel Sega fans deserved better after waiting so long. Yet, I'm still amazed by the soundtrack and remembering how jealous my Playstation friends were at the time.
