Sometimes there are ones that kind of meet in the middle.
There is one criticism I lay towards the narrative-type stuff is any that have a lot of filler to just move the plot. The Who's Tommy is a classic but half of it is under two minutes, with half still even under a minute or 30 seconds. Quadrophenia is better in this regard as it is almost entirely made up of songs and strong instrumental pieces.
