Copied my Vector ranking from a couple months back:
1. A Cell Divides
2. Puzzle Box
3. The Good Doctor
4. Veil
5. Nil By Mouth
6. Host
7. Clear
Positions 3-6 are all very closely matched, not a lot to choose between them.
I've listened to Virus 6 or 7 times so far, but it's still too early for me to rank the tracks against each other, let alone against Vector tracks as well. I haven't even got an inkling which song is my favourite yet, which is a bit unusual for me.
One thing I can say, is that if I made a compilation of my favourite Haken tracks, nothing from Virus would feature. Nothings really jumping out at me yet, but hopefully that changes after a few more listens, as I certainly don't dislike any of the songs.
