You Tubing Tuesday - Bubble Gum Pop Songs

It is a rainy and nasty day here today.  I got a whole four hours sleep last night and I feel well... Lets just say I feel unpleasant.  Therefore, in an effort to brighten up my mood, I present these songs few of us want to admit that we like.  Bubble gum pop tunes!  The rules for this particular contest:

1. The song has to be happy and cheerful;
2. The chorus has to be highly repetitive and easily remembered; 
3. The song has to have a hook in the music so that you could identify it in just a few notes; and
4. If the song is from a one hit wonder band - it is a bonus.

Now I didn't really consider the next video to be really in this category...

but Disney did this, and now it has to be included...
