Ok, look. Writing about what you know is the first rule of writing, and the biggest inspiration people get is from their own personal experiences, so ya if you have an interesting thing happen to you in real life and you can spin it into a song that makes you millions then why for all that's holy aren't you allowed to do it? Jeese Louise. I'm willing to bet that the vaaaast majority of music written is based in some way on a real event that the writer either experienced first hand or heard about and thought it was interesting. Taylor Swift is really really really not the only one who does it, so Please for the love of God, stop harping about it like some jealous twit with your knickers in a knot and just enjoy the catchy tunes and sing along to Never Ever Getting Back Together the next time you break up with your on again off again boyfriend.
