What do you think of the song Buddy Holly by Weezer?
I don't have the ''face palm'' smilie or I would use it here.
If you watch the youtube video that shows the written lyrics you see that the words are really, really bad. However, a simple catchy tune and really bad lyrics can lead to a success of sorts. Bad lyrics that have to be squeezed into the tune stick in peoples' minds.
So if you listen to last year's video sensation ''Friday, Friday'' you will see that these two songs are very similar. They sound like nursery rhymes put to music. So bad they are almost good.
