Let's rewind the clock a (gasp!) whole decade to the year 2009. Kellie Pickler was on top of the country charts with her smash hit "Best Days of Your Life" an anthem for women with broken hearts everywhere. It was my JAM! If you watch the music video (below) you might notice a young lady with long blonde curly locks jamming on the guitar and making an appearance. It is none other than at the time up-and-comer Taylor Swift, and it is pure gold. I could watch it all day. Enjoy.
