Will you suggest funeral songs for me?

My best friend, Tigh, died on the 17th. I need help selecting music to be played at his funeral. His favorite bands were Metallica, AC/DC and Slayer. I would be grateful if anyone knows what songs might be appropriate. I don’t want anything that’s too depressing, but I also don’t want things that are too hard (although my best friend would have loved it, his family might not understand).

I’ve already picked “Nothing Else Matters” by Metallica, because it’s very Tigh. We don’t know yet if it was an accident or if he killed himself intentionally, so I need to be careful about lyrics. I’m having a really hard time going through and listening to Metallica songs, because I break down when I hear a lot of them, so I just need help.

If anyone can provide links for Metallica, AC/DC, or Slayer songs that might work, please do. Thank you.
