Here are several sites with some nice kids' music downloads
This one has over 70 songs in Mp3 format for download, with most having printable sheet music as well. Songs follow a wide range of preschool and early learning themes. You can purchase a CD with all of the downloadable songs, too.
All of the Kindermusik core curriculum CDs are here, as well as many supplemental songs from the Do Re Me and You library. You get three songs intially free, and if you take a Kindermusik class, can use the code in your book to both download your class music and 7 more free songs. You can also download songs at .99 each.
There are several free songs for download here, including a wonderful one about washing hands.And lots of other thematic songs for download at .99 each, too-I've used many songs from this publisher through the years as a music teacher, and love them.
We are currently enrolling for classes at the University of Memphis Community music school, including Kindermusik!
