This nails it for me. Yet they got heavy airplay through the 70's, even into the early 80's. Dated product of their time says it all really.
Thought I would get into this Doors debate. I've always liked them, and thought that between Morrison's voice and the ever present keyboards thought they had a very distinctive sound.
The Doors indeed got loads of airplay in the late 70's and early 80's on mainstream rock stations. At the time I thought of it as a curiosity as no other band that was no longer active excepting the Beatles got the same treatment. Now I view the Doors resurgence in this time period as the very beginnings of the Classic Rock radio format where you would rarely if ever hear a new song.
