this is one of the better songs to sleep to as far as I'm concerned.
and maybe this. but they're both similarly transcendent to be awake to as well. I adore them both. Smashing Pumpkins are my favorite band with ties to the grunge scene (other than the Afghan Whigs but I'm not sure they really count): "1979" in particular is completely undeniable.
also, nah, there's no way Cantrell came up with 'grunge' in '93. pretty sure it was Mudhoney who coined the term? back in like '87? or Green River or something. I'm not too familiar with the genre (anymore) so I could be wrong about that, but it was definitely around way before '93, especially considering the year after that is when Cobain killed himself and grunge was most certainly a thing for almost the whole time he was making music.
