It's not that you can't sing, you're just not good at it.

It's actually a small insecurity of mine, people tell me I'm good at it, but I record myself and listen to and I'm just like "wow I'm HORRIBLE".

I had a guy at work, who heard me sing 3 words, laugh out loud at me. Then he told me he tells his friends about the guy at work that can't sing. So, I'm the butt of jokes to people who don't even know me.
He doesn't work there anymore, he he he :-)

Well, I guess I could show you... Here, I made a preview of a cover for Feel Good Inc by Gorillaz: https://m.youtube.com/watch?v=H-CJrSM-nv0
I'd really appreciate some feedback!

Hey man, that sounded ok to me. I don't know the original version, but I don't think that matters because what I heard from you wasn't bad. Do you have an accent that's British or Australian?
Thanks for sharing your song with me :-)

I'm just an American guy. And thanks for the feedback!
