Ah yes, I see what you mean. To clarify, my essay was proposing that Mental FM is the beautiful and mysterious phenomena of hearing songs in our heads without actively having to remember them; it's an involuntary response that brings us a pleasant surprise. While recollection certainly has its own place and power, it is not the same as Mental FM; recollection requires effort while Mental FM is an effortless experience.
Furthermore, I offered proof of this with my observation of the details of the songs playing in my head with the same clarity of the recorded track. This suggests that the songs are not being actively remembered, but rather heard upon tuning in to Mental FM. And while it's true that some of these songs may be stored in our memories, I maintain that it's Mental FM that is inviting us to listen to them at random moments. This is why I was urronged when it was suggested that recollection is the only cause of this phenomenon.
In conclusion, I stand by my suggestion that Mental FM is an involuntary response to hearing songs we had forgotten about, and that it serves as a reminder that even if we forget somethings we can still find joy in rediscovering them if we pay attention. Plus, it makes for some pretty funny moments when the song playing in your head matches the one playing on the radio.
