Here’s a throwback to simpler times, when kids’ music sounded like kids’ music. This soothing and sometimes silly collection of animal-themed faves proves that the “Eensy Weensy Spider” can still enthrall. There are classics (from “Baa Baa Black Sheep” to “Baby Beluga”) and songs introducing new friends (“Octopus’s Garden”). And if lyrics about “taking us to the zoo” give her the wrong idea, skip to the sleepiest take on “Goodnight, Irene” to date.
