To play is not really relaxing

I had high hopes because the present reviews. Compared to the previously purchased "My Romantiv Piano 1 and 2" or "Piano Solos for All Occasions" the book is but disappointing. The pieces are sometimes quite unfortunate set and not so easy to play, as assessed previously. How would it be if you in the product description sometimes examples (partial copies) reflects the individual pieces, so you can get an impression of the difficulty.
I also not only since 3 years playing the way piano.
The takeaway was great again.
