My Little Reader kids (ages 2 and 6 now) have also really enjoyed the first 3 volumes of Readeez music videos. You can watch most of them on YouTube now.

I just donated to their Kickstarter campaign, and thought I’d share the project with this board since this is where I was first introduced to their products. I have learned a lot from this forum! Thanks!
