Let's see here...I sometimes dislike the musical aspects of the sequels, but I can think of a few songs that I find really catchy and fun and others that are very sweet and emotional...if I had to pick the top five...
1. Friends for Dinner...this is just so catchy and really fun, it gets stuck in my head for hours at a time.
2. It Takes All Sorts...This is just a sweet song and the type I really love, with a message that I think many people should listen to.
3. Best of Friends...I just adore this one, it's so emotional! It really hit a nerve with me as I have a friend who's moving several states away. So yea, a very touching song.
4. No One Has to Be Alone...so pretty, I really like this one.^^
5. Peaceful Valley...another happy, fun song, really addictive.
Of course the best song will always be "If We Hold on Together", but as far as sequels go, those're my faves.
