Learning the delight in complexity of structures?

Strange thing to see through the times: While once it was enough to hear songs lasting not longer than 3 or 4 minutes, now these days it can gladly take a standard time span of 6 to 7 minutes - songs even longer than that, if they're good and well-structured, are also very much appreciated.

Yeah, I notice that 6-7 minutes for some is more like a norm.

Except for some rock where lyrics seem to deteriorate and they just repeat the same words over and over.
