I like some heavy metal
music, but agree with the people saying the screaming ruins it for a lot of bands, so I don't listen to that many metal bands. My brother does so I know some of the bands listed. Good metal is the best type of music though I think.
My favourite band at the moment would probably be Opeth (someone called them melodic death metal, which kind makes sense if you've listened to them a bit). Saw them in September and they were pretty good. There not quite as fast as some other metal, and you have to get used to long songs with Opeth, since the average song is over 8 minutes long, but that's part of what I like about them.
Some of my favourite songs:
Opeth - Wreath, Deliverence, April Ethereal, Epilogue, When, Demon of the fall, Karma, Black rose immortal (20 min 14s), Funeral Portrait, Credence (no metal), Black water park, The Draper Falls, The Leper Affinity, Master's Apprentice, Ghost of Perdition, The Grand Conjuration. Plus a few others
Metallica - Sad but true, To Live is to die, Holier than thou, The God That Failed, One, Harvester Of Sorrow, Master Of Puppets, Sanitarium, The Thing That Should Not Be, Orion, For Whom The Bell Tolls, Fade To Black, Of Wolf And Man etc
Rage Against The Machine - Calm Like A Bomb, Guerilla Radio, Bulls On Parade, Revolver, Killin In The Name Of, Wake Up
Tool - Vicarious, Triad, The Grudge, Hooker With A Penis (stupid name, good song), Stinkfist, Aenema, H, You Lied, The Pot, Jambi, 10 000 days.
Karnivool - Pretty much anything off the Themata CD (Lifelike

Cog - My Enemy (

Plus many other songs, by lots of different types of bands.
