True, but did your little brain tried to think about the line " Kahe Mochi bhi khud ko Sunar" ... Well if you can not understand I'll expalin it for you.
This is a rhetoric line in which write is making fun of someone caste by comparision.
Infact I will say, not the line whole song should be deleted, and every person invloved in this should be probed, especially writer.
