Mine would be:
1. Odyssey (my all time favourite song, closely followed by A change of seasons from DT)
2. The Edge of Forever (This is why Pinella is my favourite pianist)
3. Lady of the snow (most haunting song ever?)
4. The Accolade II (haunting, beautiful piano.. again
)
5. When All is Lost (the piano, and Russell's melodies + the first melodic guitar solo... sends shivers down my spine every time)
6. Church of the Machine (Pinella again.. and the amazing chorus!!)
7. The Sacrifice (best.. vocal performance.. EVER!! Seriously, the second verse is SO intense with Allen's vibrato, really breathtaking!!)
8. A Fool's Paradise (Everything clicks well together here, great riffs, and another amazing prechorus+chorus)
9. Awakenings (So epic, in less than 10 minutes.. and again Pinella is my f*cking hero..)
10. Paradise Lost (modern classic.. The clean riff leading to the outro/ad lib choruses and Russell's voice before that is such a great climax to a beautiful, heartbreaking song)
As you can guess, my favourite part about SX is the piano parts by Pinella, which is why I miss the haunting, mystic approach to their ballads instead of clean guitars leading the songs (Swan Song is still pretty good, love the 3 minute mark with only Pinella and Russell)
