It looks like you only use this function once. Instead, I think we should call this `updateScoStatus` and have it set `MusicComms.isScoEnabled` for us. That is:

```
updateScoStatus: function() {
  if (this.enabled) {
    this.mrc.getScoStatus(function(status) {
      this.isScoEnabled = status;
    }.bind(this));
  }
}
```

That's still not really "beautiful", but I think it's good enough for a temporary workaround for 1.3.
