Hi!
Many happy returns to your baby!
May I suggest some PRECLASSICAL music for your wife(and not only, it is good for the baby too).For you, there are so many classical stations on the radio, some with excellent broadcasting quality and solid selections, and ...they are free!
Regarding what to start with, please try not to go in a predefinite direction.Instead, listen to anything and let your soul and mind to get in love with what is more naturally suitable for your sensibility! You could end falling in love with classical music!
Regards,
Octavian
