Me?Singing?

Singing? I like it, but my voice seems to get sore when I reach to high tone. I'm also thinking of joining the Gold Mic. Competition. Singing? There ain't much songs for me, because NO LOVE SONGS ARE ALLOWED! I'm better in singing these, u see. Some which are not love songs, and I can sing quite well, it will be either too boring or the time is too LOOONGGG.................. It should be around 5 minutes, thats too long.... the limit is around 3 minutes, So Ba Bui! I wish I can sing melodiously.... I believe in my self.... :-) JIA YOU!
