Islamic State of Iraq and the Levant (ISIL) in recent weeks imposed a Taliban-style ban on music and smoking in Raqa, declaring them un-Islamic.
In a statement it said it would "ban the sale of music CDs, music players, and playing songs in cars and buses and in shops and all places".
The group added it had taken the step because musical instruments and singing are "proscribed in Islam because they distract from remembering God and the Koran".
In a second statement, ISIL said as part of efforts to "apply sharia (Islamic) law... it is completely forbidden to sell cigarettes or water pipes in any place".
Such bans are reminiscent of those the Taliban imposed on television, cinema and music in Afghanistan when in power up until 2001.
