ELI5: what is happening in our brains when a song becomes "old" to us?

For instance, I will be listening to this one song I really like, but after overplaying it I lose my appeal and actually start to dislike it. Why?

One theory of music is that the composer/performer is playing a sort of game with the audience.  They provide patterns for the audience to try to anticipate.  When the audience can't see any pattern at all, it just seems like boring noise.  When the audience can follow the pattern perfectly, it is also boring.  When they can follow some of the pattern, they are pleasantly surprised by the exceptions to it.

This means that when you've perfectly learned all the twists and turns of a song, it no longer surprises you, and becomes boring.

I don't know if there is an objective "right answer" to this question, but this seems to fit.
