6. 'All Apologies'
"All Apologies" originally appeared on In Utero, but the version everyone remembers was recorded in November of 1993 for Nirvana's MTV Unplugged album. Watching the performance after Cobain's death, it's hard to hear it as anything but a suicide note. "I wish I was like you," he sings to his huge global audience. "Easily amused." It ends with him repeating the line "all in all is all we are" 13 times.
