Excuse Me
I didn't want to be unpleasant and rate this a zero in the event that I am completely incorrect, but this melody is from a Vipzone Midi Pack. Specifically the Roxx the Club 3 Pack, if I did my research correctly.
In other words, it's not your own melody. I'm not really experienced when it comes to the legality of audio submissions, but shouldn't you have to let listeners know where the melody really comes from if it is not your original work?
Please correct me if I'm wrong, and sorry I bothered you.
