You were my idol, just when I thought I'd give up on everything
I heard you play this familiar melody (melody, melody, melody…)
When his old friend think about giving up caring about B.o.B, he hears that familiar melody (the one that plays in the background), an indirect way to say B.o.B plans to go back to his roots.
Could also be a reference to his song “Do you have the stamina” off Bob vs. Bobby Ray (one of his best mixtapes), since the melody in this song is similar to the backing melody in the other song
