(I then got it to give me an example of a well-known song in Am and it replied "Love me to death" by Type O negative, of all things. That's actually in G# minor - interesting the web in general does a really bad job of guessing what key that's in too, most of the responses from a google search say F# major! I'd think "Stairway to heaven" would be about the best known song in A minor - looking at some of the Google results I suspect part of the problem is interpreting the "A" as the indefinite article rather than the note name?)
