I noticed DS loved choo choo soul by Disney at daycare so I bought it. Sometimes it's the only thing that keeps him quiet in the car. It's not bad, we can listen to it without wanting to poke our eardrums out after 15 minutes. Actually the songs are pretty catchy.
I really like the Wee Sing CDs. I also bought this. I like it because it's familiar kids' songs, but they're not sung in an annoying way. And, I've heard great things about Caspar Babypants.
DS loooooves Raffi and Sharon, Lois and Bram. We also do a lot of kids radio on the pandora, which is great when we're in the car and he goes to grumpy town!
Re: Best kid song CDs?

I love Name Your Tune CDs. They record your babies name in the songs--and not after the fact either. Each name gets it's own CD recorded.
