anyone use those websites

or apps that you hum into and it tells you what song it is? I wrote something, but I'm not 100% sure I wrote it or am remembering it from years ago or what.. So, I thought I'd play it into one of those apps or whatever to see if it was recognized.. No, sure didn't, which SOUNDS good, until I play Highway to Hell or Stairway to Heaven and it doesn't recognize them, either...

Just wondering if any of them are reliable..
