If you’re looking for new preschool / elementary music, or if you’re a parent of a little one, you will love the Zooglobble blog! Stefan Shepherd, the man behind the blog, reviews preschool albums that parents can actually listen to on repeat without going insane. Check out this post on the Best Kids Music for 2010.
While the site is not aimed towards teaching dance, music and dance go hand in hand, so it is a great resource for any preschool teacher. I have found a lot of new music and sometimes the artists he features will offer free downloads. The posts usually have some way to preview the songs, artists and albums they are reviewing, so you can see if it will work for you.
