Completed Frontiers and I'm sure like most everyone else I've seen this theme jumped out as my favorite the moment I heard it and reminded me immediately of Infinite's theme. Even though it's been made by many I wanted to do my own rendition with Infinite's non-lyrical themes since the pitches are easier to adjust to than the lyrical version for this. I'll see about making my own lyrical rendition of sorts in the future. This combo is already one of if not my favorite ever though. Love this theme and most of the Frontiers OST!
A Mashup of "Find Your Flame" from Sonic Frontiers, and pieces of "Infinite 1" and "Infinite 2" from Sonic Forces. Also a small bit of Skynut's "Phantom Infinite" song he made.
