It's never too early to corrupt a child's musical tastes, but sadly, you can't just shove a pair of white earbuds into the womb—not without a lot of work. The solution?

The Ritmo Advanced Pregnancy Sound System shares pretty much any source that's got a headphone jack (iPods, Blackberries, etc) with a baby via a speaker-filled strap. The strap wraps around an expectant mother's stomach, connects to an audio regulating breakout box and shares her playlist with her unborn child.

But even if the baby doesn't appreciate the effort, any participating third trimester mother with aching joints and a bulbous gut protrusion gets to feel like just like that party-ready green shadow chick—we're absolutely certain. $130. [Ritmo]
