It sounds like a cheap, knockoff anime intro song. I wasn't a fan at all. Didn't feel climactic, it just felt a bit jarring and out of nowhere. It certainly made the scene memorable, but it took away any sense of triumph from the ending too.
It's still better than Lifelight though, which is an absolutely awful vocal song that clearly wasn't ever meant to be a vocal song.
Jump Up Superstar is pure class all the way through though! (Though Fossil Falls/Main Theme is actually the true best song in the game!)
