i have a sweet, amazing, powerful voice. thanks! :P

A man's voice cannot be sweet and beautiful. It's used for female. He has a powerful voice. His voice is warm and comforting.

You would not describe a man's voice as sweet, as this is used for female singers. You can say: “ He has an absolutely amazing voice” “ He has a rich, awesome or powerful voice " A song can be described as: a ballad, folk song, romantic, charming, exciting, calm, powerful, pumped, rocking, quiet, loud, etc.

you can say you have a sweet voice. you sing beautifully. you sing in a beautiful way nice song sometimes i say a beautiful/ wonderful song
