There are a couple different options, from adding album art, or fixing metadata. But every time I tried to do one of those options I would get this message. 

Ok cool.  I'll fix 100 songs and see if I like it.  But when I could click on anything the app would go dead. 

Ummmm ok?

Tip - Your app demo should make me want to buy it.  It should make my life easier.  Rainbows and butterflies should start flowing out of my computer because of your app.  It shouldn't be endlessly annoying.  

So goodbye TidySong.  It looked like such a promising relationship.
