Suddenly, and without any warning, a rap song appeared on social media, produced by three young men – who were unheard of up to that moment – and racked up millions of views in record time. The track was entitled "Long Live the People", based on the slogan of the revolutionary youth (especially notable in the 20F’s manifestations) directed against the monarchist slogan: “long live the king”. The track topped the list of most-watched Moroccan videos on YouTube. This is unprecedented for an agitational song, as the top spot has typically been occupied by pop trifles.

The epidemic has worsened, infecting 2,024 people, of whom 126 have died (as of 15 April, 45 days after the first infections) according to official data.
