My daughter was definitely affected by music before she was born. I had two LPs for Christmas when I was 7 months pregnant and played them both a lot. She kicked and fidgeted all the time whe Elton John was playing but was still and relaxed for the Mozart Horn Concertos. She asked for a compilation tape to be made of her favourite music when she was four and listened to it every morning before going to school. It included the Mozart but not Elton John!
