Not really sure what Amazon's been thinkin', but somebody last month must have said, "Hey, you know what would be cool? Free kids' music!" And, then, actually followed through on that idea, because now there are a handful of free EPs for the digital downloading, with easily 15 to 20 good songs worth your time. Justin Roberts leads the pack with his, er, Snack Pack EP, featuring songs from 5 of his albums. You probably have some of these already, but maybe not the earlier songs ("Little Raindrop" or "Billy the Bully"), and if you don't have any of them, then get over there pronto. The real find in the craziness is Roberts' fellow Chicagoans Bloodshot Records' Fun For All Ages sampler, which includes seven tracks from four fine albums, Songs for Wiggleworms, Wiggleworms Love You, Animal Crackers, and The Bottle Let Me Down. Do not hesitate in picking up this album, the Alejandro Escovedo track is especially lovely. But that's not all. VeggieTales aren't for everyone (particularly if you're not religious and you're listening to their Bible-based stuff), but their silly secular stuff can be fun no matter your denomination or lack thereof. Their Five Super Silly Songs EP is exactly that; it includes versions of a couple songs that were big hits on Kids Place Live, "The Hairbrush Song" and "The Pirates Who Don't Do Anything." What's that? You want more? How about some Sesame Street? Their Amazon sampler has a more energetic version of "Ladybugs' Picnic" than you might be familiar with (but it's still good) and also features "What's the Name of that Song?" You can also pick up an EP from the Wiggles as well as a Cedarmont collection and a sampler from a Rockabye Baby-style knockoff called "Cradle Rock." Not my thing, those last two, but your mileage may vary.
