Morningrise:
Absolutely beautiful melodies throughout, wonderful acoustic passages, so much raw emotion, brilliant.
One of the downsides is that some of the songs aren't structured too well - riffs are somewhat pasted together.
Advent is a cracker, but after the initial thrill of it dies off, it isn't the best on the album.
The Night and the Silent Water is a classic, it's so beautifully emotional.
Nectar is the weaker link, although still being good, it has a few weak moments.
Black Rose Immortal is a wonderful epic masterpiece, but it could probably benefit from being a bit shorter. The middle-section is possibly the greatest thing Opeth have ever written.
To Bid You Farewell won the song survivor, and I can't argue, it's Opeth's best clean-vocal song.
My Arms Your Hearse is still the best though, in my opinion. Blackwater and Morningrise both close behind.
