IoT App Development for Playing Music

Only highly experienced developers should bid here. Everything can be done using IoT. I'll not explain this thing to any developers. Many fraud marketing guys waste my time because those fools don't know how to work. They first themselves waste our time then again they contact some developers in their contact and ask them to waste our time again. I'll file a complaint against such people to freelancer for sure if they will waste my time in this project. We need a centralised app which will be setup at our home in some device or server, we should be able to store any music or any videos in that. Whenever any member need they should be able to listen or watch videos any time on their mobile. Each member of your family has a different taste in music. With our App, there should not be any need to have a separate music player in each room. We should be able to Load all songs to a central server and let each member of your family enjoy music on their smart phones - anytime, anywhere! Source code will be our property. Designing part will be done at your end.
