Well, I definately have more Land Before Time songs that I really like than those that I don't enjoy so much, but I'll just list seven of the ones I especially like hearing and why.
On Your Own (VI)- I love dramatic songs, and Littlefoot is such a great singer, so having him do this solo was quite pleasant. It starts with his feelings, then ends with his realization. He actual learns while singing. He has quite the impressive mind which displays nicely through a well written song.
Peaceful Valley (II)- Loved the melody and the significance of most of the lyrics like "Every cloud in the sky, green leaf on a tree, is reminding me, far away dreams really do come tru-u-u-ue." I also liked the way they divided each character's parts at the start. And the fact that it is the only Land Before Time song at the present that starts at the beginning of the movie, but stops and doesn't finish until the credits.
Both vesions of Remebering that I am aware of (The Star Day Celebration and The Missing Fast Water Adventure)- Very pretty sounding song. Ruby sings them so well, and they have a good message about never forgetting what is really important. The one from TSDC really adds to the special feeling too.
Friends for Dinner (V)- The is humorous how Chomper and Littlefoot sing it feeling one way, while the other three who sing feel quite differently. The lyrics don't agree with the times, (soup, stew, a la mode, etcetera) but the song is still fun to hear with its updeat rhythm.
It Takes All Sorts (IV)- Very nice hearing a song against racism in a Land Before Time kind of way. It's Ali's only song, but at least it has a very important message while showing how beautiful of a voice she has. And it shows that Ali can learn a lot faster than most humans. She learns about accepting others in one day, then sings about it as if she had known all about it her whole life. "It takes all sorts to make a world. Short and tall sorts, large and small sorts. To fill this pretty planet with love and laughter. To make it great to live in, tomorrow and the day after... The brightest way, the rightest way, according to reports is simply to take all sorts." Wow. She managed to deduce all the secrets of accepting all types after learning the concept in less then a day. She's amazing!
How Do You Know? (XIII)- Littlefoot has been giving his wisdom to others from the beginning of their friendship. It was nice to hear him finally question himself and have the other three who can sing help him understand what to do. It really shows Petrie, Ducky, and Cera's wisdom truly shine. The dramatic tune completes the moment.
All Land Before Time songs are made for a reason, even if that reason is presented unpleasantly and/or is very difficult to find and understand. And if a song is made mainly to pass the time, make the movie/epsiode a bit longer, and appeal to children who like songs, well, that's still a reason.
