In the first verse, E-40 acknowledges that success in the music industry is often not based on talent but rather on politics and hype. He mentions how some artists receive fame but struggle financially due to record sales, unrecouped expenses, and video budgets. He boasts about his own experience and longevity in the game, highlighting that he doesn't need to explain himself or prove his skills. E-40 then references other artists' achievements, like being on the Billboard charts or receiving an MTV Award.

E-40 emphasizes the temporary nature of success, as it's only a matter of time before someone new takes the spotlight.

He refuses to conform to these expectations and mentions his dedication to networking and connecting with his fans. E-40 asserts his confidence in his independent approach and mentions achieving success through the underground scene. In the third verse, E-40 addresses the lack of recognition he receives compared to other artists who are often featured in The Source's "Hip-Hop Quotable" section. He suggests that people might not fully grasp his lyrics because they are not listening closely enough. He mentions his extensive discography and the need to prove himself, highlighting that he earned his deal based on his skills rather than a short verse. E-40 also references the late rapper Tupac Shakur and wonders what he would do in his current situation. He questions the ethics of journalists who often portray rappers negatively. E-40 mentions his ranking on a list but dismisses its importance, stating his allegiance to a magazine named Murder Dog rather than Blaze. Overall, "To Whom This May Concern" is a lyrical tirade against the fickleness of the music industry, the struggle for recognition, and E-40's determination to stay true to himself.
