“Angelus” is a love song about deep attraction, loyalty, and celebrating a special woman. The song blends Nigerian Pidgin, English, and Afrobeat slang, giving it a relaxed and street-pop feel. The singer portrays himself as someone who may have a “good boy” or “bad boy” side, but when it comes to his girl, he is devoted. He promises to sing, dance, call the heavens, and play instruments for her, using Angelus as a symbolic expression of his love and admiration.
