Instead of a top 5, I'll give you a top 10...

01. CMX - Talvikuningas

A magnificient concept album by the finnish band CMX. Now, CMX is a very old band but this was the first album of theirs I ever bought. It's a concept album (scifi-opera

) with magnificient finnish lyrics such as "and his tomb is guarded by one hundred thousand killer satellites". The story is well presented and pretty complex. The songs seague seamlessly into each other. "Talvikuningas" (Winter King) is an outstanding album and it was not a hard choice for my #1 spot.
Song highlights: Kaikkivaltias, Tähtilaivan Kapteeni, Punainen Komentaja, Kaikkivaltiaan Peili
02. Phideaux - Doomsday Afternoon

Doomsday Afternoon is an album that my friend Lux from #fin familiarized me with. It's the second part of a three album series by Phideaux. Genrewise it's symphonic prog without a lot of the instrumental noodling the genre is known for. The songs are mostly acoustic, melodic, relaxing and very beautiful. Doomsday Afternoon could be described as easy-listening prog, but I don't really agree. It's way too complex and layered for that.
Song highlights: Candybrain, Crumble, The Doctrine Of Eternal Ice (Part Two), Formaldehyde, Microdeath Softstar
03. Turisas - The Varangian Way

Simply - the greatest viking metal album ever. The only thing Varangian Way lacks is bad songs. The whole album is an epic ride with the ancient varangians on their journey from north to Constantinople. If bands such as Moonsorrow, Finntroll or Falkenbach are to your liking, you'll simply love The Varangian Way. I don't think it'll ever be topped in this genre.
Song highlights: To Holmgard And Beyond, Five Hundred And One, The Dnieper Rapids, Miklagard Overture
04. Sonata Arctica - Unia

Unia was an album that pretty much divided Sonata Arctica's fans into two camps. Others loved it and the rest hated it. Me? Well, obviously, I think it's the 4th best album of 2007. I never liked the double-bass drum, super high bpm of the earlier Sonata. Unia slows things down and takes in a lot of progressive influences. Tony Kakko uses his voice in a much more varied way when compared to before. I really hope Sonata Arctica continues in this direction because their earlier albums simply can't complete with Unia.
Song highlights: In Black And White, Paid In Full, It Won't Fade, My Dream's But A Drop Of Fuel For A Nightmare, Fly With A Black Swan
05. Nightwish - Dark Passion Play

Nightwish's first album without Tarja Turunen was a great success. The Poet and the Pendulum alone is probably the best female fronted metal song ever and the rest don't fall far behind. The one thing Dark Passion Play suffers from is its lenght. Skipping one or two songs (Eva and Last of the Wilds come to my mind) would make the album much tighter and probably make it flow better. Regardless, however, DPP is a great return from one of my first favourite bands.
Song highlights: The Poet and the Pendulum, Amaranth, Master Passion Green, 7 Days To The Wolves
06. Pain of Salvation - Scarsick

There's not much I can say about this album that hasn't been discussed to death by now. I know a lot of people hated it for a variety of reasons, but I like it a lot. Granted, I haven't been listening to it much lately, but it's still one of the best releases of 2007.
Song highlights: Scarsick, Cribcaged, Kingdom of Loss, Enter Rain
07. Porcupine Tree - Fear of A Blank Planet

You probably saw this one coming, didn't you? I'm not the biggest Porcupine Tree fan but there's no denying that Fear of a Blank Planet is a brilliant album. The reason I'm not rating it any higher is because I still don't really like the last 2 songs. The first 4 are brilliant but it kind of ends there.
Song highlights: Fear of a Blank Planet, My Ashes, Anesthetize, Sentimental
08. The Flower Kings - Sum of No Evil

If you've heard any previous Flower Kings albums, you'll know what to expect from Sum of No Evil. It's the same old symphonic prog delight that they always deliver. It's a great album but there really wasn't anything new so it gets the 8th spot.
Song highlights: One More Time, Love Is The Only Answer, Life In Motion
09. Dream Theater - Systematic Chaos

Systematic Chaos was good, but not really as good as I wanted. I can't really rate it higher because I find myself rarely listening to it at all.
Song highlights: Forsaken, The Dark Eternal Night, Repentance, The Ministry Of Lost Souls
10. Kamelot - Ghost Opera

Kamelot's The Black Halo is probably my favourite power metal album ever. Ghost Opera couldn't really surpass that and kind of fell flat on it's face. Don't get me wrong, it's a great album and easily surpasses 95% of all other power metal albums. That gives it the last spot on my list.
Song highlights: Rule the World, Ghost Opera, Blücher, Mourning Star
