On guitar easy songs

Another novel popular on the Kindle I read recently was The Hunger Games by Suzanne Collins. I don't quite understand why it's so incredibly popular, but it is a good story well told. And the writing is pretty specific and detailed. One problem I had was the way it kept introducing new innovations from the future to threaten the heroine. That's especially true of the dogs that seemed to be the already dead competitors at the end. How could that be? And I just didn't find the whole premise to be credible. The United States -- no mention of the rest of the world -- has collapsed and been replaced by a tyranny wielded by one city over the rest of the country, divided into sectors where people are worked like feudal farmers, for the benefit of the city. The heroine doesn't spend time playing guitar easy songs.
