Input: A Mistake . To be honest, I must have hit a button by mistake which caused me to order something I really hadn't intended on buying.  There was no way to cancel it on-line so I figured I'd give the CD a listen, since I had Nellie's first CD, which I love.   I must say, I was disappointed.  Just seemed like every song sounded the same.  Maybe it will grow on me, the more I listen to it, but kinda doubting it
Output:
NEG
