Speaking in terms of writing, I tend to get most of my inspiration from music. Sure, I'm not the world's best author - nor do I think I'm even good enough to be considered an author, but it's a passion that I indulge in for the sake of making myself happy. Likewise, I listen to music that suits my mood when I start to write. However, certain songs have proven to aid my creative spark a lot more than others - regardless of my mood.

Currently amongst said songs are:

12 Stones:
Fade Away

A Perfect Circle:
Let's Have a War

Blur:
Song 2

Bon Jovi:
Everyday
Wanted Dead or Alive

D12:
Purple Pills

Eminem:
Just Lose It
Mosh

Evanescence:
Hello
Lies

Ginuwine:
Pony

Gorillaz:
Left Hand Suzuki Method
Sound Check (Gravity)
White Light

Linkin Park:
Hit the Floor
In the End
PPR: Kut
(the last one's on Linkin Park's Reanimation disc, but the disc's info - according to Windows Media Player - lists 'cheapshot & jubacca' as the artist.)

Nine Inch Nails:
Closer
Dead Souls

Papa Roach:
Last Resort
She Loves Me Not

Puscifer:
Rev 22:20 (Rev 4:20 mix)
The Undertaker (Renholder mix)

Rehab:
Hey Fred

Staind:
Epiphany
Mudshovel

Steppenwolf:
Born to Be Wild

So, there you have it, arranged by artist. There are many more, but these are the ones that usually produce some sort of good creativity within me.
