I can see the hilariousness of this too since it has a completely quirky and funny feel to it too. Sonic Adventure 2 was probably one of the very few Sonic games I enjoyed since it had the chao garden and such.
The guitar sounds great. The bass and drums are also awesome. The synth has a an awesome sound to it too. Excellent loop too, nice work there.
Overall, awesome song.
Please contact me if you would like to use this in a project. We can discuss the details.
