In the "ways to make yourself feel old" category, 25 years ago today, Nirvana's behemoth sophomore album Nevermind hit the top of the Billboard album charts -- the first grunge album to do so. I'm not going to go through the accolades and accomplishments of Nevermind, but suffice it to say, it is widely regarded as one of the greatest albums in rock history.
The video I'm going with is for the song "Lithium." It only hit #64 on the Billboard Hot 100, but it's my favorite of their songs from Nevermind for which a video was made. In true grunge style, the subject of the song is dark. It's about man who turns to religion after his girlfriend dies, lithium being a reference to Karl Marx's quote that "religion is the opiate of the masses." Lithium, of course, is a drug used to treat depression and suicidal thoughts, which makes the song even more poignant, given that Kurt Cobain killed himself a few short years later. How grunge.
