I use to have the same a few stone ago Miss D
It certainly helped. It is of course a personal thing as we all have differing musical tastes and different things spur us on, and these can change at well too. The ones I can remember from my playlist then are
Right here, right now - Fatboy Slim
Hey Boy, Hey girl – The Chemical Brothers
Bohemian Like You - The Dandy Warhols
Pumping up the stereo – Supergrass
One more time – Daft Punk
Sandstorm – Darude
MacArthur Park – Donna Summer
IF (BIG IF) I was to do it now, off the top of my head I would probably include some of these
Slam – Pendulum (If nothing else the thought of the video would make me smile)
I’ve got a feeling – Black eyed peas
Pump it – Black eyed peas
Any of a few by Def Leppard
As for cooling down, twas always Enya
