“Music and rhythm find their way into the secret places of the soul” Plato

We're looking for suggestions on some good songs to include for HJ to listen to.  We plan on playing music, through headphones on Liz's belly, so that HJ will have some tunes that will soothe her/him when he/she is born.  We'd like a good mix of genres and feel that there is a place for all types of music.  Please leave a comment with the name of the song and the performer.  Thanks much.
