I Don't Understand

I just don't understand how most popular song now don't seem to have any meaning behind them.  can understand having songs that make you want to dance and sing along, but most songs now are completely random. For example, Ke$ha's song "Dinosaur" has no point to it except to just sing something. I'm not saying this because I don't like her, cause I do, but she doesn't have a purpose to sing about dinosaurs. I just heard a song by Christina Aguilera today that I never heard before. "I'm OK" was a powerful song about her dad and what he did to her mom. That song has a purpose and was wonderful. I'm sure that most songs have a purpose, but not like they use to. I'm Ok by Christina Aguilera If an artist had a very bad breakup they would write a sing about it and make it fun. I just can't stand  having songs that are about nothing.
