the Iron Blue Intention remix is great. Honestly, the 3rd party that got the worst musical treatment after the Square guys is Sonic, imagine your only arrangement not even being composed for Smash. There's other musical nitpicks I'd make (like how Fates, for all the problems it has, had a great soundtrack, and it only has Lost in Thoughts All Alone like 3 times, the Tellius games featuring no remixes whatsoever, Life Will Change somehow not being in Mementos), but I'd still consider Ultimate take on music to be an overall improvement over Sm4sh, where I can't say anything really stood out when I heard it, not as good as Brawl however.
I do hope that if Nick gets in, he comes with a little more music compared to
, that comment from Sakurai that they where hoping to get somewhere between 10-20 tracks for Terry makes me hopeful at the very least (well, besides how Terry got treated in general in the end).
