Normally I'm not one for posting more than one song at a time, but 4 just popped into my head when I read this thread.
Popcorn - I always remember this one from when I was a wee little tyke. Not surprisingly, both my boys liked this when they were little.
Music Box Dancer - Even though I was a teenage when this came out, it has always stuck with me.
Frankenstein - What a jam!
Rock And Roll (part 2) - This one always makes me want to get up and yell. Okay, they do yell "Hey", but it is primarily instrumental.
