Musical genres have gotten confusing

I’m kinda clueless about some of the newer musical genres and sub-genres that are being talked about nowadays. I know what synthpop is, I used to listen to it in the ’80s and I still like some of it (like Depeche Mode and the first Nine Inch Nails album), but I don’t understand why “electroclash” is considered something different. It sounds exactly like what we used to call synthpop. But then again, some of the stuff that’s now called synthpop doesn’t really sound like that at all, but more like poppy EBM. Or is that “future pop”? Someone help me out here?
