I have, with great smugness, noticed that many folks (mostly the young'uns) have little or no idea who sings some of the older (I mean, 70s and 80s) music, let alone someone like the Andrews Sisters (who?) or Patti Page (who???)
Example: Kung Fu Fighting was sung by a one-hit wonder, a rather obscure foot note in the music history books, Carl Douglas. I've seen the song Kung Fu Fighting attributed to:
The Monkees, Michael Jackson, and (gasp) even the Bee Gees.
The first few times I saw such anomalies, I was amazed, I was like: "I didn't know MIchael Jackson did a cover of that...." only to download it, and find out he DIDN'T.
And notifying people of mis-labeled songs does NOTHING, they don't care, and probably can't figure out how to use their own email in the first place.
