Assalama alaikoum,

This hadith: "Singing makes hypocrisy to grow in the heart like water makes herbs grow." (Al-Baihaqi 10/223 and Abu Dawud no. 4927).

Lets assume this hadith is authentic. What is this hypocrisy that grows in the heart? What are the consequences of this hypocrisy that is growing in the heart and what will happen if somebody keeps listening to music and the hypocrisy is keeping growing in the heart. Will it reach some point that the 'maximum' of nifaq is reached in the heart'? And will happen than, do you than become a munafiq by just listening excessive music?
