Beware the wall

The classical approach must be carefull not to fall into the error of making the arrangement more important than the "song." Which mistake we could call the "wall of sound effect", from the "wall of sound" technique associated of Phil Spector:

He buried the lead and he cannot stop himself from doing that. If you listen to his records in sequence, the lead goes further and further in and to me what he is saying is, "It is not the song... just listen to those strings. I want more musicians, it's me." —Jeff Barry (Wikipedia)
