The songs would be:
KoRn_ Here to Stay. An ironic little song, taken with the context of it being a funeral.
Jimi Hendrix's cover of Bob Dylan's All along the watchtower. I love that song.
Metallica_ Nothing Else Matters. A personal song for me.
Beastie Boys_ Fight for your right to party. I think that would be hillarious to hear at a funeral.
Beatles_ Yesterday. Another personal song.
ACDC_ For those about to Rock (We Salute You). OY!!
Tool_ Lateralus. I think that would be awesome to hear given the meaning of the song.
Whitesnake_ Here I am, Rock You like a Hurricane. Just when you least expected it.
Guns and Roses_ Paradise City. Self-explanitory.
Rage Against the Machine_ Mic Check. No real reason for choosing this one, I just like the song.
Soundgarden_ Rusty Cage. At the time, I'll have broken mine.
Nirvana_ All apologies. It's somewhat fitting.
Smashing Pumpkins_ Today. That's fitting.
That's all I can think of for now.
