Iabsoluty have to agree with frankvg on this
Volume adjustment is a must in music
You might want to just try your hand at getting the song and re-producing it into a song on your own machine...
If the song plays a few chords, go find some syncs in your library that qould fit the sounds...
Or maybe play ot out in piano or a different instrument
I like it, although personally I think that you should have adjusted the audio volume for some paths, I mean its kinda chaotic with every layer at the same volume.
Please contact me if you would like to use this in a project. We can discuss the details.
