I’m not sure, I haven’t paid attention to how long most songs are.  I might speculate that this length is more convenient for listeners to remember, so songs tend to end right before it is about to be too hard to remember them.

So, people get bored in that time and want something different?

Well, it’s certainly common for songs to have similar topics and style, with short refrains of lyrics or music.  This can be reminiscent of how the composer or performer learns to sing a song, but the form is also a very convenient way for a song to end.

Maybe that is the longest they can wait before airing a commercial on the radio?
