Several German tracks from Dr Slump ( the new series) are available on an anime compilation CD called ” Anime hits II”. (I tunes link) In brackets I’ve tried to ID either the Japanese song name or where it appears in the show).

Those are:

12) Mondgesicht ( Opening Theme)

13) Megaherz ( Hello, I love you)

14) Aus Dem Wig ( Arale Parale!)

Fans may  interested to know tracks 4& 5 are Japenese versions of DBZ themes. With track 6 being a German dub DBZ song!
