Lack bonuses

I think the artist is no introduction so I just use a precise subjective language. The pun in the title of the album should you put a flea in his ear.
I stayed on my end by listening when the disc stopped after playing 13 songs. Let me explain: On the cover are indicated 6 bonus shares following the 13 songs but they are totally absent from the disk, even a hidden track at the end of the last title or before the first.
If anyone knows how to make an appeal to obtain the missing securities, thank you to indicate this by responding to this comment.
