What was the anthem of your teenage years?

The anthem of my teenage years would likely be "Teenage Dream" by Katy Perry. Its upbeat melody and lyrics perfectly captured the exhilarating feeling of young love and carefree moments. The song encapsulated the thrill of that age, celebrating friendship, nostalgia, and the desire to live in the moment. It became a rallying cry for many of my experiences during those formative years.
