My daughter got the doll for Christmas and how big was the disappointment when we found out that the doll concurrently as a condemnation only one song and then pauses. My daughter has it fallen anyway, but I was very unhappy. Wanted to send them already, but now read the customer reviews for this product. Thank you for your comment Daria. Under the dress the doll on the back actually a plastic tab that you can pull. Lo and behold, you really sing both songs clearly. So it is neither on the battery nor a defective chip! Since this regard to remove the plastic tab is nowhere recorded, gets the doll from me deducted a point, because I had not read the aforementioned comment, I do not know still, how to make them sing. I hope all those to whom it is issued as well as to have helped us, and I wish them a lot of fun with their singing Barbies.
