Works with Some Songs

I just downloaded this app, and it has worked well with more than half of the songs I have wanted to edit. I have another program on my PC which I use, but I am trying to just use my MAC… The app was cheap, and with the price I am happy with the product. I wish I could figure out why it will not accept some songs when I drag them in. Not sure if the songs are too big or not.
