Oxford Dictionary says-
"rock music that appeals to an older generation, or that is heavily influenced by that of an earlier era"

We would like to think of it as songs you know and love, and have heard countless times before from the
soundtrack of your life. You have heard these songs in movies, commercials, and heck even when you are
standing in line at the supermarket. Songs that even reach beyond "just classic rock", but also can be found
in country, motown, and blues too
