I used to be hugely into Melodic Death Metal, and my interest in the mid nineties Swedish scene has recently returned. These are my recommendations, with those in bold being quite easily the best the genre has to offer:
A Canorous Quintet - Silence of the World Beyond
Ablaze My Sorrow - If Emotions Still Burn
Amon Amarth - Sorrow Throughout the Nine Worlds
At the Gates - The Red in the Sky is Ours
At the Gates - With Fear I Kiss the Burning Darkness
Cardinal Sin - Spiteful Intents
Ceremonial Oath - Carpet
Crown of Thorns - Eternal Death
Decameron - My Shadow...
Dissection - The Somberlain
Dissection - Storm of the Light's Bane
Embracing - I Bear the Burden of Time
Eucharist - A Velvet Creation
Eucharist - Mirrorworlds
Excretion - Voice of Harmony
Gates of Ishtar - A Bloodred Path
Godgory - Sea of Dreams
Infernal Gates - From the Mist of Dark Waters
Lord Belial - Unholy Crusade
Miscreant - Dreaming Ice
Necrophobic - The Nocturnal Silence
Necrophobic - Darkside
The Moaning - Blood From Stone
Sacrilege - Lost in the Beauty you Slay
Unanimated - Ancient God of Evil
But of course, the greatest melodic Metal album to emerge from Sweden is, and always will be, Sacramentum's Far Away From the Sun.
