1. To enjoy some piece of energetic music, especially rock and roll, by singing or dancing along to it. A crowd of nearly 20,000 fans rocked along to the songs of the ultra-popular boy band. I was so embarrassed when I walked into the kitchen and saw my parents rocking along with some song from the '70s.
2. To continue progressing without difficulty or hardship. With the success we attained so early on, many of us had the delusional mindset that we could keep rocking along without making any real changes to the way we did business. Our country had been rocking along so steadily for the last 20 years that we were totally unprepared when the economic crisis hit.
