Phil spector referred to the singles he produced as:

He called them "teenage symphonies." This was mainly because a large part of the market for these new songs that used the new "wall of sound" technique were in their teenage years. With rock and roll music just coming onto the scene at the time that Spector was beginning his production work, the young-adult market was looking for someone who could bring a high level of production and artistic acumen to the world.
