Your surprised that they played songs about Moshiach? Moshiach is a basic tenant of Judaism. Something the Christians Stole/Borrowed from us. See Maimonides. In regards to their cult like passion for the Rebbe, It is veneration of a great leader - one who changed the landscape of judaism, not worship. Finally, as others have noted, this is a response to a shot that the leaders of Reform Judaism took at Chabad. Chabad is not in the business of knocking other forms of Judaism, but won't allow others to drag its name through mud. And yes - a jew is a jew regardless.
