better solution? I want to observe the playlist for changes. how would i do this without setinterval? In my opinion the best way is to wait for the IPC socket if something happened. Is this possible?

xmmsclienttest.js

var xmmsclient = require('xmmsclient'),
    util = require('util')

var client = new xmmsclient.Client('blackcat');

client.onconnect = function () {
  console.log("Connected!")
  var oldID
  setInterval(function () {
    client.playback.current_id().onvalue = function (id) {
      if (!oldID || oldID !== id) {
        client.medialib.get_info(id).onvalue = function (propdict) {
          metadata = xmmsclient.PropDict.flatten(propdict)
          console.log("Currently playing " + metadata.artist + " - " + metadata.title)
        }
        oldID = id
      }
    }
  }, 1000)
}
client.ondisconnect = function () {
  console.log("Disconnected!")
}

client.connect("unix:///tmp/xmms-ipc-blackcat")
