As always music is up for interpretation for the individual. As many of you posted there is a market for their light hearted music. When I think about all that is going on in the worlod ( husband is a Marine and can go back to war at any given time) I can appreciate a little bubble gum pop. Lets take a look at who is buying their music...TEENS. From preteen to very early twenties. They may not want to want to listen to Adele, Melonie or jazmine because many of their songs are not relateable for that age demographic. I'm in my twenties and I have been throught hell and back so when I listen to "It Kills Me' I know whats up. I know that specific pain that Melonie is singing about. All in all, there is always a market for light bubble music especially for the kids. Hell when I was a kid I listened to Backstreet Boys, Nsync even Will Smith lol. And as i have grown so has my taste in music. Don't bash Katy for simply making music that can cater to specific people who do not always want super deep music blasting from their ipod. Just my opinion.
