"But I can't remember who is in my CD player now"

This quote by Eric Roberts is most likely referring to the sensation of being overwhelmed by the amount of music available to us in the contemporary age. With streaming services, CDs, and other digital music sources, it can be tough to keep an eye on what we are listening to. The quote recommends that Roberts is feeling overwhelmed by the sheer quantity of music available to him, and he can't remember what he is currently listening to. This could be translated as a metaphor for how we can become overwhelmed by the amount of information and choices readily available to us in the modern world. It can be tough to monitor what we are doing and what we are listening to, and it can be hard to bear in mind what we are presently focusing on. The quote is a pointer to take an action back and concentrate on today moment, and to bear in mind what we are currently doing.
