Underworld - Dark and Long (Dark Train Mix) ... If you can get over the Trainspotting cold turkey/baby crawling on the ceiling backdrop, this one has lots of energy, can be played on a loop and will keep you going for a long, long while.

Hüsker Dü - Eight Miles High ... For the more anger driven workout with Bob Mould yelling in your ears for four minutes.

Elder - The Falling Veil ... They'll take you on a 11 minute journey with ups and downs and turns and some top stoner rock along the way.

Slowdive - Star Roving ... You know that feeling when you stumble over a new track (some years ago at least) of a band you loved back in the day, and they still have that same chemistry and energy? Yeah, this is one of those for me. Partly the song itself, partly being happy they still got it. Good times.

Chug - Flower ... Anyone remember that Pete & Pete episode where they race around the house with their bikes? That's that song. Every time it comes up on random selection, I get a bit of that "school's out, not a care in the world, let's just race bikes" vibe.

Honourable mentions: Sabbath/Supernaut ; Broken Social Scene/7/4 (Shoreline); Petty/Running Down a Dream; Soundgarden/Jesus Christ Pose
