Conduct a walk with a group of people listening to the same music (over headphones).
Ask some of your good friends, people from work, neighbourhood or any other specific audience you like or plan to spend some time with to join you for a music walk outdoors in the city or in the nature. Plan a route which you like to share and create a playlist with songs that relate to the places you plan to visit. Make sure everyone can listen to the playlist at the same time. Guide them through your route and take care of the traffic.
