like a karaoke interactive feature we can have with other players and/or a music player for music we can upload and play in the room while we're having events (e.g. parties, etc.)

Also, maybe a 'voice message' machine where we can leave voice messages for our neighbors/friends that only the owner would be able to listen to would be interesting. And maybe a recording machine that the owner can record messages, save (store maybe like 10 recordings) to playback later.
