54. "Spank Thru"
A good argument can be made for "Spank Thru" as the song that started it all. Dating back to his 1985 Fecal Matter demo, it was the first Cobain-penned song that got Krist Novoselic's attention, thus kick-starting the formation of Nirvana. "One of the songs on [the tape] was 'Spank Thru,'" Novoselic recalled in a 1992 interview with WFNX music director Kurt St. Thomas. "He turned me on to it, and I really liked it, it kind of got me excited. So I go, 'Hey man, let's start a band.' We scrounged up a drummer, and we started practicing. Took it very seriously too." Once the band had mobilized, it became the third Nirvana song to find official release (finding its way on 1988's Sub Pop 200 compilation) and has continued to make appearances on most of their official live albums.
