Is the 'pop' not considered a metal possibly referring to the 'pop test' for Hydrogen gas that I had to do hundreds of times in high school?

I'd say it's because pop is the most commonly played music genre, just as hydrogen and helium are the most common elements.

I'd like to point out that astronomers don't always refer to non-H/He stuff as "metal". When you start talking about exoplanets, asteroids and meteoroids, there's a different classification (albeit nearly as reductive): | I'd like to point out that astronomers don't always refer to non-H/He stuff as "metal".

Each of these has much less variation in density and volatility than the variation between categories (I listed them in ascending order of density and descending order of volatility), so these tend to stick together both in terms of what stays on a planet and in terms of forming layers on a planet (e.g. Earth has no Gas, a light dusting of Ice in the form of the biosphere and oceans, Rock crust and mantle, and a Metal core; Neptune's outer layers are Gas, most of the planet is Ice, and the core is Rock and Metal).
