This turned out to be Dragons by Aleksi Virta, which is freely downloadable from Last.fm.

Damn, I love this album!

My PC isn't currently connected to my amplifier, so I need to buy a new optical cable.

What you see here in Last.fm is by no means all that I've listened to, as until I get the cable, almost everything I play is on the CD deck.

It took a while, but I got there. I really must get the PC re-wired to the hifi, so that I can use it for playing music all the time.

Anyway, for the sake of posterity, and as a matter of public record, track 5,000 was the title track from… (drum roll):

Emerson, Lake & Palmer - Tarkus

These are both recommended for anyone that likes IDM:

Erin Anderson - Intermezzo http://www.jamendo.com/en/album/4491/

Sharp - As Days Get Shorter http://www.jamendo.com/en/album/3596/

Ah, my first journal entry.

I just realised that I played an album by Khan, then an album by Can.

Completely unintentional, but there you go.
