This is Sonic 30th Anniversary Symphony's cover of Sonic Unleashed's main theme- Endless Possibility. Man... I miss Unleashed so much... I remember playing Sonic Unleashed on my Ps3 and I enjoyed it. I don't care what people say about Sonic Unleashed but- Sonic Unleashed is the best Modern Sonic game to ever be released and I don't care what you say or people say. Also, I edited a part out and made this a little louder in BandLab so you might wanna turn this down. I also, put this song in a WAV file so you can enjoy this more. (Also, they got NateWantsToBattle to sing this cover and it was amazing)
