It's true, or at least it looks to be true. January 31st, in just a few days time, Bosworth will release a new Kraftwerk Songbook, called "The Best of Kraftwerk Songbook". The songbook contains arrangements for piano, vocal and guitar for 12 Kraftwerk songs, all collected from their 1970's albums "Autobahn", "Radio-Aktivität" and "Trans Europa Express.
As all song titles on the back cover of the book (at least the now publiched version) are in German, I'd expect all lyrics to be written in German, but who knows - the book could be bilingual.
The complete list of songs:
Autobahn
Kometenmelodie 1
Kometenmelodie 2
Radio-Aktivität
Ätherwellen
Antenne
Ohm Sweet Ohm
Trans Europa Express
Metall Auf Metall
Schaufensterpuppen
Spiegelsaal
Europa Endlos
