I was thinking more lyrically. 'West Coast' talks about living in the West coast, people drink, people sway to the music, people fall in love with the films and music, it's just the way of life out here, especially if you actually live on the coast. 'Shades of Cool' is her singing about a man whom she loves who loves her back but put her second to drugs, who rather be high and wander the world having fun than settle down with Lana, how she wants it to be.
