Amy has been an aspiring singer for years. She used to have a website that portrayed her as a country singer. She's also been on the Duggar's tv show for years. In light of that, I wonder why she didn't take voice lessons, learn to play the guitar, write music, etc. These are all things that make you competitive in Nashville. It seems she's handicapped herself by just winging it and really not honing her craft. She's a little old to be so unprepared, IMO.
Amy is nice enough, but I think Jim Bob had a point in explaining that her goals are a little lofty, especially for someone who really isn't ready.
