Another Laurie Berkner fan. Also, the Signing Time CDs have great songs about friendship, sharing...and educational ones re: letters, counting, colors. Look them up on YouTube to see some of the music videos.
I have to say, our daughter's favorite soundtrack is Jersey Boys (oldies like 'Sherry Baby' and 'Big Girls Don't Cry')--makes for a nice break from the kid music that the parents can enjoy as well ;)
Andy Z is a local musician who does lots of local concerts for tots--uses puppets, plays the guitar, etc. Kids love him. You can download songs from his website, buy his CDs at his shows & check out his schedule. Lots of times Moms' groups sponsor him at local events, malls too so they're free & the kids dance, sing--lots of fun! www.andyz.com
