IMO, he’s one of the best singers there is, just because there’s no one else that sounds anything like him. The first three albums were masterpieces, not so much lyrically, but not many bands could have pulled off songs like Soma, Rhinoceros or Zero… if Billy Corgan were to die at around 1996, the Pumpkins would have been remembered as one of the greatest bands of all time… but, lulz, he’s still alive… think about it, if Kurt didn’t top himself, Nirvana would’ve been forgotten… anywho, Corgan is an amazing musician and writer… just disregard pretty much everything he did after the late nineties… he lost his talent like Trent Reznor did, but that doesn’t mean his old stuff is worthless.
