Music everyone will like

Lately we've been playing some tapes my sister gave me to soothe the savage beast LB becomes in the car. She hates sitting still for too long -- especially on the long drive home Wednesdays from my mum's house after work (tired and in car equals bad for babies unless they can quickly drop off, which LB has lost the knack to do). The tapes seem to be working, but they drive J and me to a lesser extent batty. There's a couple of Play School songs that I always get stuck in my head. There's nothing worse than hearing Noni singing when you're trying to get to sleep...
Anyway, if you want something cooler, Slate has a roundup that looks interesting.
LB seems to prefer rock, anyway.
