I appreciate that you made that song however for your next song keep 2 things in mind please:
1. Dont make pasages overlaping - so when one line start at 200 the previous line must be over the latest at 200 as well not only at 202.
2. I am sure to be part of a minority on this but while singing I actually have to breathe every now and then so please keep the gaps in the music file that the artist uses for breathing to let the players breathe as well during them rather than stressig the previous tone until the next one starts.
