5/10 it's actually my least favorite idol song in the game despite this song (along with Reincarnation) being used in quite a bit of promotional material for TMS#FE, I'm more into Yashiro's Black Rain (that I've posted before). Tsubasa is one of my favorites though.
It lives up to what you'd expect to hear from the title, but it doesn't do too much for me as a piece of music because it doesn't really seem to have much of a strong melodic base to it, relying more on ultimately uninteresting "machine" sound effects instead. I'm sure it serves its purpose well in-game, though. 6/10.
8/10 yeah I can definitely see this fitting a racing game, upbeat and fun so certainly nice to hear on the race track (or maybe as a menu theme). The beginning sounds very familiar though, so it's going to be stuck in my head for a while until I figure it out lol.
