There are a few songs from this series I used to like as a kid:
On Your Own: from The Land Before Time 6: It's not a bad song, but I don't really like it.
Lone Dinosaur: also from Land Before Time 6: I like the country western thing, but, it's not true to the Land Before Time series in my opinion.
You're One Of Us Now: from The Land Before Time 2: The half-singing half-talking during that song got annoying for me after a while.
It Takes All Sorts: from The Land Before Time 4: I can't believe I liked this as a kid. The voice actor for Ali didn't have the best singing voice in my opinion. Darn song is stuck in my head as I'm typing my reply to this topic. Argh!
Grandma's Lullaby: also from The Land Before Time 4: This song wasn't my favorite but I didn't hate it. the voice actor for Littlefoot's grandma didn't have the best singing voice in my opinion. Plus that song gets stuck in my head for weeks after watching the movie.
Friends For Dinner: from The Land Before Time 5: I kinda still like this song; it's just that the voice actor for Chomper has one of the worst singing voices in my opinion. Fingernails meet chalkboard, chalkboard meet fingernails. Plus he sounded like he had a cold.
Imaginary Friends: from The Land Before Time 9: Yeah! In my opinion, Petrie's voice sounds like fingernails meet chalkboard, chalkboard meet fingernails in my opinion.
Me And My Dad: from The Land Before Time 10: The voice actor for Littlefoot in this song has too high of a singing voice in my opinion.
