In this song, John Mayall & The Bluesbreakers explores the concept of having control over one's emotions. The metaphor of having a padlock on the blues represents a sense of ownership and control over his own feelings. He doesn't necessarily sing the blues like traditional blues artists, but he has his own unique style that expresses his emotions. Mayall acknowledges that some critics may have different opinions on how he should express his emotions, but he urges his audience to pay no attention to envy and to stick to their own style and emotions. He admits that he never knows what he'll find once he unlocks his mind, but he's willing to explore and express his emotions through his music. Overall, "Padlock On The Blues" is a song about embracing one's own emotions and finding their own style of expression. Mayall encourages his audience to join him on this journey of self-discovery and to not be swayed or discouraged by external critics.
