Kinda but also true that most long pieces have one or two movements that are the popular ones and you have to wait till you get to it. e.g. Ode to Joy is 45+ minutes into the Ninth symphony, Mozart's Rondo alla Turca is the third movement of the K 331 sonata, etc.

Though I feel very bad writing ^^^. The rest of those pieces are very worth listening to. I listen more often to the first movement of the Ninth.
