The Thumbelina soundtrack has music by Barry Manilow and lyrics by Bruce Sussman & Jack Feldman, and all the songs suit the mood and style of the movie perfectly. And (with the exception of maybe Soon) all the songs flow into the movie so well that the story depends heavily on them. One of the main reasons I love Thumbelina was because of the music, so of course I have the soundtrack, the cover of which is below.
You can buy the soundtrack online from amazon.

The pages also contain audio samples, which have been clipped to less than 10% of the original song according to unlicensed sampling criteria, and are meant for information purposes only. Please don't ask me for the full mp3s, and support the people who created this music for us to appreciate.
