Sorry to hear that. I mean it with all sincerity that your music is good. Still I can relate. As much as I care about critical reception and viewer reception good and bad. (Elvis once said "There's no such thing as bad publicity) I was hoping to find at least one paying customer. That said I don't give up.

Hey hey, you can always come back in a few years and watch some cartoons? You'll find that creating a platform as a music maker is effing existentially depressing sometimes. I wish you luck in the future but some advice: interact with your communities as much as possible! I've been a part of a few separate music communities and they're all basically the same. It can often feel like your trying to step on your peers as you promote yourself but your peers are also the ones that elevate you the most.
The beatbox scene in New York pushes a "beat box family" theme, I've noticed people on Newgrounds do it too. Follow your dreams Dmitry! You will always be accepted back here with open arms.
