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.
