I know we have film, music, literature, musicals, etc for pop culture - so does that mean any song? Should say, Happy Birthday be entered under pop-culture? What about classical — It's still popular, and was really popular once, right?
And what about food? Is food considered a pop culture item? I had no idea what a mallomar was until very recently when I actually looked it up on the internet. I, for some reason, would probably consider Cheerios to warrent an entry, as it is a brand name, but then again.. I don't know.
