Miller wrote this as a road trip song. When he was a kid, his parents took him on long road trips where they listened to radio stations the whole time and sung along to their favorite songs. In the '70s, FM radio allowed for stereo sound and provided a cleaner signal, so Miller made his road trip anthems bigger, with more layers to the sound. He made sure these songs were upbeat and fun, just like the ones that caught his ear as a kid.
Another characteristic of Miller's road songs is mention of various places - El Paso shows up in this one. In "Rock 'N Me
," he namechecks several cities, including Phoenix, Atlanta and Philadelphia.
