Yes but you that you are only reading these songs only skin deep. Truly you have to listen between the lines. All these songs share the same meaning and story. Taylor can't keep a man so she decides that in order to get back at 'the man' she will write super popular romance song for tweens and young women. Knowing she will make millions and become super popular, all while laughing at the men knowing we will never get this. Thus making her free to now play with the hearts of men everywhere. So you see these songs are actually very deep and complex. Now it's time for a male artist to strike back!!!
They can certainly be looked at as deep. Especially 3 of these 4 songs. But no matter how you look at it Never Grow Up, Long Live, and Innocent can't be about getting back at a guy. In fact, when I listen to Innocent, it certainly does sound like she is referring to a guy she knows, but she is saying how it's never too late to undo the things you've done. Everyone deserves a shot at forgiveness. If anything, that song seems like she is saying that she is willing to forgive the guys who she thinks has wronged her if they decided to apologize.
Long Live has her battling the fondness of nostalgia in exchange for optimism about the future. I can see Mean being a slight towards some boys she's known, but it's still mostly directed towards her critics.
I don't see how she is trying to get back at guys who have no chance of becoming as popular as she is when John Mayer, Jake, and Taylor what's his face were all extremely famous as it is (not to mention, that One Direction guy). I definitely do think she is cunning and that in some ways she does use these men to advance her career, at least in the sense that she writes songs about them (but really, every other pop star/pop punk band does that too), but not in like an outwardly mean-spirited way.
