For me I tend to go for really lively music to get me in a good mood. Turn up the volume and enjoy!
One of my all time favourite tunes (typically cheesy 80's style vid):
YouTube - The Jam- Town Called Malice
And another favourite of mine, very lively again (Not a music vid as such, just a pic with song playing) :
YouTube - Private Hell - The Jam
And just to finish another great tune :
YouTube - Elvis Costello and the Attractions - Oliver's Army
You can probably tell I was a bit of a Mod by the time I was 10 yr old!
I have also been listening to Poets of the Fall lately, really good band I must say. Got into them after hearing Lift me Higher at the end of the 3DMark 05 when you run the demo.
