Contrary to some, it is not vinyls. Rather, it is vinyl. Please make a note of it.

This issue came to my attention twice yesterday: once on Twitter, where someone griped about people using the term "vinyls" to describe more than one record; the other instance occurred while perusing Sonic Boom's holiday zine, in which a clerk informed its readers that vinyl is indeed the plural term for vinyl (the same principle applies to fish, buffalo, and sperm).

I am guilty of occasionally using vinyls, but it's always deployed in a tongue-in-cheek manner. When you know the rules, you can break them—but only once every three months. It's in the manual. Trust me.
