Portable jukebox

Recently there have been many more music discs added with great music, i think making a portable jukebox that you can take with you and play as you go along would be a great addition. For example, in a ''SMP'' like server, you could walk around a district where a lot of people visit often and they know you are coming. Also it would make just generally travelling more fun. It is much better than lets say, an option to choose a song from the minecraft OST to play as it is more rewarding getting different music discs and having a different experience adventuring!
