recordings cannot benefit from the 20-year extension unless they were published before the 50-year term expired. I think I've found out what made me pause when reading this: they implicitly assume that previous works will automatically have their protection extended. Of course this kind of logic only works in the whole "copyright" kerfuffle of corruption. Money can even buy you works in the public domain back, if you missed to lobby in time for a new ex post facto extension.
