i used to have a major hard-on for this type of music, although still love it, i dont nearly listen to it as much these days. post melodic death songs that you like, or used to like at one time
Aside from those bands though some melodic death metal can be pretty good. Death's Symbolic was one of my favourite albums for a long time and I still really enjoy it from time to time.
I'm a fan of melo-death. The Absence, Dark Tranquility, At The Gates, Scar Symmetry, In Mourning, Insomnium, old school In Flames, Soilwork, The Haunted, etc. It doesn't help when your two closest friends are huge melo-death fans. Well that and tech-death.
