Thank you for quoting lyrics of songs that you consider vulgar. Are these included in the list of banned songs. So, the first song says "drink milk, you look week; It is raining, don't leave tonight; Hey Gujjar, drink milk" and the second one say " don't knock just com in" There are have been many such songs in Urdu and Punjabi that have similar lyrics, many of which are considered classics. A lot of classical Urdu and punjabi poetry is also similar.
Perhaps it is a sign of changing times.
Which milk :)
