Meaning of "Why Took Your Advice" by Grandaddy

The lyrics of "Why Took Your Advice" by Grandaddy seem to reflect themes of disillusionment and disappointment in relationships. The protagonist of the song listens to the advice of a friend and makes significant changes in their life, such as disconnecting from the constant noise of cable television, trying to find enjoyment in music through fixing the radio, and seeking a deeper understanding of the world by purchasing a microscope. However, the friend who offered the advice does not seem to reciprocate the effort or commitment, failing to follow their own guidance and failing to maintain communication. This can be interpreted as a commentary on the idea that relationships require mutual effort and communication, and when one person consistently fails to uphold their end of the bargain, it can lead to feelings of loneliness, frustration, and a sense of disconnect. The protagonist's sense of isolation and longing for connection is palpable in the repeated refrain of "How come you never call?", highlighting the lack of reciprocity in the relationship.
