Nirvana's "Smells Like Teen Spirit" just came on. I remember watching that video for the first time late at night on MTV, sometime in fall/winter 91-92. I don't want to say that it changed my life, as that's a tad dramatic, but it was revelation for a somewhat musically sheltered kid from rural adjacent Wisconsin. It definitely opened new vistas of music, art, and ideas. And that video is still cool AF.
