I love to sing
I wish I could sing so I could be a singer or a vocalist.
Everyone can sing. It takes the just interest 
Practice requires too much time and dedication. 
That is true but you must have the interest first, then dedication will be easy
Even though I wish I was a singer, I think singing is better suited as a hobby for me. Some people sing for religious devotion. How about you?
That is true. I sing for religious worship like rdgabmomoh 
What kind of styles do you sing? I enjoy pop and rock and even a few traditional styles like Chinese Opera.
I enjoy alternative and rock
I heard rock is usually focuses and centers around the electric guitar and drums.
