"You know that song that goes....?" I say that all the time, and I have a fairly good memory for that stuff. I might even attempt to whistle the song in question, but that can be a challenge with things like, say, "Flight of the Bumblebee".
Even then it doesn't help much given alternate names, sampling, etc. What is it, the theme from the Lone Ranger or the William Tell Overture? And in case anybody remembers MC Hammer and Rick James, how likely was it that you'd know that "Can't Touch This" sampled "SuperFreak"?
So unless I happen to run into the right people, how do I find a song I'm trying to remember from a few bars or musical phrases? Is there some sort of search tool for this?
