How do we “hear” songs in our head (not from an outside external source)?

Question

Last night I had a song “stuck in my head” for hours. It was there, palpable, as if there was a radio right next to me. Obviously that wasn’t the case, but how do we “hear” these memories?

Answer 1

Ongoing research. I’d say most probable cause being that it’s not only about how the music is received through the prefrontol cortex and other regions but also the physical geometry of the stored information. If the geometry fits a specific pattern (the ongoing research) the song represents a contextual anxiety reduction.
