Well when most people say The Smashing Pumpkins are grunge they only mean Gish and Siamese Dream which the two songs you named aren t on either I still don t consider those 2 albums grunge either and few sources do as well Other than that I agree with DrumstickJuggler s points completely If you really want to we could re examine citations and do the whole grunge listing again to get a new consensus of which bands are grunge based on citations mixed with discretion For instance 7 Year Bitch s article doesn t list it as grunge and neither do most of the citations I ve found about them Most citations consider them both punk and riot grrrl but not grunge For all I know there could be other bands like this on the list who really aren t backed up by citations
