The song talks about how a song can bring you anywhere at any time of the life you have. Nostalgia is an element that would really, have you awakened in the world you always wanted to be. Have you ever felt something good that you cannot explain while hearing a song in the air coming through the radio speakers in a car nearby? or house? or room? or from a hum from the lady you met at a convenience store? or a kid singing his favorite song that was taught by his grandpa?
There is magic in the words and melodies songwriters put into their songs as they try to pour down emotions they feel while creating the material.
