I really couldn't care less about her or even anyone in the music industry for that matter. I do think though that she's justified in how she comes up with songs. First she learned about music through country which is derived from folk and blues, which is basically story telling music. With the shallow life that she living you quickly run out of things to make songs about, she's either touring or doing other things that the majority of her fans can't relate too. So she creates scenarios, and her songs keep hitting number one.
If it's really that annoying to you then stop listening to her newer music. It's just contradicting how people whine about her and then buy her music.
