Worth it?

So one of the new Rock Band tracks this week is Hier Kommt Alex by Die Toten Hosen. Some astute Guitar Hero fans will recognize this as one of the bonus songs available in Guitar Hero 3 and pretty much anyone will be able to tell from the title that this isn't a song that originated in an english speaking area. All the lyrics in this song are in German, and I honestly need to consider whether it is worth two dollars just to enjoy myself and others totally failing at singing a song in german.

This YouTube clip shows just how difficult it could be.
