Greg,
I don't remember where I saw the discussions I mentioned, but it would probably have been one of my favourite running sites. Maybe try www.coolrunning.com or www.runnersworld.com
Here's some more of my favourite songs to try. I find different songs work on different days, so here's a range of what I've been using:
'Walking on Sunshine'
'Rock star'- N.E.R.D
'Concrete Boots'- After the Fall
'Run On'- Moby
'Roadrunner'- Joan Jett
'You and your Hand'- Pink
'Run Baby Run'- Sheryl Crow
'Dancin with Myself'- Billy Idol
'Painkiller'- Pendulum vs. The Freestyler
'The Last Song'- Foo Fighters
'All These Things I've Done'- The Killers
'We're Coming Home'- Rogue Traders
'Hurricane'- Faker
Happy running!
Amy
