Yes, this film is a Baby Boomer advertising vehicle with not-to-subtle product placements. But, it is also a story about a woman who learns that she can live two dreams - pursuing rock 'n roll and loving her estranged family. She blends both with the symbolic trio of braids in her 80's hairstyle that represent her three kids who she left behind for a rock life in LA.
Could she have lived both dreams and stayed with her family? From the arguments she has with her ex-husband (Kevin Kline) it is clear that a domesticated life is like a trap she has to bang against. She is clearly happiest and most comfortable when on stage jamming with her band the Flash. It all comes together in the film's final scene.

I am inspired by these two actors who are 65+ and live life to the fullest - both on screen and off.
