95. "Cut Me Some Slack"
"We walked in; we jammed the song," Grohl told KROQ about this 2013 rager, the only song that Grohl, Novoselic and touring guitarist Pat Smear have recorded together since Nirvana ended in 1994. "It just came out of nowhere. The best songs happen that way. We recorded it live and put a vocal over it and that was it. It was three hours and it was perfect." The vocals on this raucous jam for the Sound City soundtrack featured a little-known guest singer named Paul McCartney, whose Sixties-era recordings are said to have inspired the melody of Nirvana's "About a Girl." What the three-hour session yielded was honestly not much of a song, but it did win the Best Rock Song Grammy earlier this year, beating Black Sabbath the Rolling Stones and Muse. DOUGLAS WOLK
