Help me ID a song on Supernatural - please!

[Newt]

Help meeee!

(I am asking here because it is music: perhaps it should be in the television forum?  Figured more might read here.)

This is making me crazy: I know I know the song and I know I will be feeling incredibly stupid when I finally get the answer, but I am drawing a complete blank and in the interest of what remains of my sanity it is desperation time.

The song that Dean had playing in the Impala when he drove up to witness the final battle.  Just the intro was played, but it is distinctive (and I  should know what it is!!!)  The song's intro features four beats of a few words in an almost goofy sing-songy voice - in German?  - and then goes on completely differently. I know this song.  ARRGH!

OK I am all braced to feel dumb.  What is it?

[Jack]

Rock of Ages by Def Leppard?  That starts with "Gunter glieben glauchen globen".

[3mnkids]

Yep, Rock of Ages.. perfect song for that scene BTW   

[Newt]

YESSS!!! Of course that's it!

Thank you Jack and 3mnkids!     Now I can stop butting that wall and get on with things.
