how old was taylor when she started singing?
She starting singing country music at 14 years old in Nashville!
How many albums have she sold?
I have no idea, but her debut album was released in 2006 and peaked number 5 on the Billboard hits. She's done very well for herself!
What kind of music inspired her
She grew up with country music, and had a single called "our song" that she wrote and performed herself. So i'd say her roots are in country music.
Is she from a music family?
I'm not sure. Her second album was released in 2008, and I think she started to get more poppy then. 
thanks
She also won 4 grammy awards, and she was the youngest album of the year winner. That's pretty amazing!
