My God... that was nice!
it is always nice to see other people's submissions and realize how much you've yet to learn. That was an experience! It was interesting - daring to explore tempo-changes, to have different themes, etc. - and well-composed, with plenty of instruments and themes to make it sound whole. It sounded professional to me, in ways that my own music never does.
And on top of that, your Nitro-Music Rumble page is well-organized (you've been doing it for some time, nice!), you provide .mp3 instead of .wav which I appreciate, and you are just a friendly fellow!
In other words...
...Congrats on another banger!
