I went to listen to this song fully expecting something really terrible after reading the comments.
I thought it was rather nice. I can hear the things some of the others mentioned, but they aren't that bad. If the song is done for a songwriting demo, it works for me.
However, constructive criticism is what makes us better, and they had some valid points.
I constantly have to remind myself to "Sing with confidence".
Keep on writin' and singin'!
