Seriously why. Sonic and the Black Knight was the last one and it was also the last time you could beat the final boss to a kickaas buttrock theme song. Why don't we have this anymore?
The Sonic Colors one is particularly bad. Colors was probably the last 3D Sonic I played
I mean, all vocal Sonic tracks are bad, but I can laugh at how cheesy Toot Toot Sonic Warrior and Live and Learn are. The 2010s ones were just kind of normal boring pop songs
Hey at least that open world Sonic game had some interesting screamo emo songs apparently
