The demo has been created to explain how to mix vocals with other instruments, there are many effects used (the typical state of the art effects used in the industry). The song itself is not “common”, because it’s a blend of different styles all together. Considering it as demo, I love to blend styles.
As always, I wish you a great listening and use always very good speakers to have the best audio experience.
If you have good headphones, it’s ok as well. Better to use good headphones than bad speakers.
