For CDs:
The 8 songs have been very well received and replayed.
Songs 1,3,5,7,9,11,13 & 15 are complete instrumental.
Songs 2,4,6,8,10,12,14 & 16 are then stop to play along.
This means that when these songs is represented (for the most part) and Bass Drum only.
For some, there is a piano and a second guitar as accompaniment.
Conclusion:
Super Lernbuch ... a little pricey, but it is indeed an export from the United States.
