Steve,
Good plan! :)
Luckily, my kids are still very young (girl=2 years and boy=6 months) and I started singing to them and playing them music in the womb. Yes, in part because we thought maybe classical music would actually improve their math skills (and with the parents they have Lord knows they'll need all the help they can get!) but also because I wanted them to love music and appreciate it in a way few people of the current generations do.
I still play them music every day, in addition to musical shows such as "The Wiggles" and they like it, although they have different tastes. My son likes quick-tempo classical, while my daughter is a big fan of big band jazz and classic rock (I've indoctrinated her since conception with Rush.) :-)
Who knows if they'll continue to love music. Hopefully the recent trend of pop music getting away from that rap garbage they call "music" and moving to acoustic stuff will continue, and they'll keep growing in their appreciation -even if only from pop music - but who knows. All we can do is guide and pray in this regard.
