Music has always been a constant presence in Rob Jr's life... from when he was a newborn (with the gentle sounds of Rockabye Baby) to a constant stream of kids' music that we've fired up for him wherever we go.

Lately I've started having him listen to "non-baby" music, including rock, jazz, and electronica (mostly when I'm alone with him, as my wife isn't too crazy about what she calls "my" music). He enjoys it immensely, at first completely silent as he absorbs the track... then pretend-jamming on whatever he's holding like a guitar (today's instrument was a toy baseball bat). Pretty hilarious to see him jam along with Muse and Jimmy Eat World.

What are your thoughts on music for your LO? Age-appropriate music only, or sharing your personal musical tastes with the baby? Any favorites emerging?
