How would I scroll a NSStatusBar I came up with a temporary fix but if 
there is a better way please tell me.
- (void)timer:(NSTimer *)t {
    if (scroll) {
      if ([info length]>5 && lasts != [info length]-4) {
          [musicMenuItem setTitle: NSLocalizedString([info 
substringWithRange:NSMakeRange(lasts, 5)], @"")];
          lasts++;
      } else {
          lasts = 0;
      }
    }
}
