When I was pregnant with DS I tried playing my bump with a variety of different music to see what he responded to, and the one thing that made him move around loads was norwigien lack metal
But I also made a point of finding a nice soothing song that I could sing along with to him an continue one he was orn. (Farewell and Goodnight by the Smashing Pumpkins) And this became his nursery rhyme.
I have found that once he becomes familier wit a song it works great to sooth him, like a song they did on boogie beeies aout favorite food and the theme from come outside. If I have difficulty getting him to settle at night I sing this to him and he stops crying. So I think its def worth a go, great way to bond with your baby too.
