I'm a singer too! The only thing I can post is this bad video of me that someone posted in youtube. But it's not my best, we cover here one band from Serbia.
Yes!!! definitely i can sing, i would probably score my voice quality when it coms to singing as 5, wherein 10 is the highest. As i have noticed if you feel the song your singing inside you, you will get to voice out your good voice quality, so tips in it, is to feel the song your singing.
