Online video show rooms to watch videos together already often have been a topic here, like the introduction of YouTube Social. Possibly because of the lack of technological standards such applications foremost now become available to listen music together. But opposed to video show rooms, these apps are not able to fetch online resouces and do require the upload of some music files.
Here are two applications to listen music together, the MuMu Player and Listening Room. The use of both services is similar to video show rooms and instant chat applications. By submitting a name a chat room becomes generated, which happens at the MuMu Player immediately and at the Listening Room after registration. When a room is generated one is able to upload music and to invite friends to start listening and to chat. For more visit the homepages of MuMu Player and Listening Room.
