My new little son is only about 8 weeks old, but already has definitive tastes in music. Nat King Cole is probably on top of his list of current favorites, but he also likes this kinda weird Loreena McKennit (sp?) disc that 2x6 recommended. KebMo, Gregory Isaacs, Dennis Brown, Bob Marley also elicit smiles and cooing. He likes Mozart, but not Handel, and the Flight of the Valkyries made him scream and cry.
Got any other suggestions for making baby happy?
