"Maybe I'm Amazed" isn't even a good song. "I Want You Back" is a great song.
Totally disagree that Maybe I'm Amazed isn't a good song - I think it's a great song...certainly one of the very best solo Beatle songs...but I'll take I Want You Back too...the best Jackson 5 song and one of my favorite Motown songs...killer arrangement and one of my favorite bass lines.
