I found a simple truth. That songs are nothing but slogans. Be it military marches, love songs, or even instrumental music. When used at the right place at the right time, it eats your logic and your brain will become like swiss cheese. When they chant democracy, songs should not brainwash them by saying "revolution! revolution forever!". They've got to think real hard what democracy is, not distracted by the truly ever heartbraking sound of the word revolution -- or Allah, or Allah akbar for that matter. But how effective those phrases are. They give you the assurance of your identity, and that what they do.
