There is an idiom in Hungarian, that says for a newborn is every joke new. (Is there an equivalent in English?) Proof in your case: newborns cry quite often you can not know these songs,you are much too young! <3
Similar results here, I was actually surprised I couldn't name the band playing Blackhole sun,but I remember the video,I found it so cool,was one of my favorites back then. Marky Mark was easy,I had a crush on the New Kids on the Block,he was collateral damage. In these years I was mostly listening to German rock and punk,the result would be much better there.
It's not art. I'd call it a form of art to invent such things for kids and torment parents. I would laugh myself silly, that's for sure.

playdoh (I think it was a runner 2 years ago):
The chocolate figurines for St. Nicholas should be fallic symbols too. Somehow I don't really like this theory. :-P
And the mostly wooden memorial headstones ("kopjafa" in Hungarian) look certainly the same as the obelisks mentioned before.
