Obviously, these sorts of things are always open to debate about choices -- and that's the point of them. And I get that something must be done to help winnow down the contenders. But if you're going to call it the 25 best American plays of the last 25 years, it should be possible for a playwright to have more than one play (it's 25 best plays, not playwrights) and I'd argue that excluding musicals is equally arbitrary.
