Playing Guitar (Hero) Again

On a side note, I'm well under way on beating Expert on GH. I rock in every meaning of the word. lol...

I've got back to playing my guitar more (finally), and I must say I feel kinda stuck.
I haven't done much new of late.

I'm thinking of writing a song, and I have the material to do so, but no lyrics.
However...

The gears are turning.
That's my expression for "i'm thinking about it".

What do you guys think? It's kinda strange to ask the internet questions, but seriously...

What topic do you think I should choose? Any ideas? I want to pick something unique.
Something close to me, but no mushy cliché love song.
It has to have meaning... I don't want it to be silly, otherwise I'd pick randomly.
I want it to be GOOD. Something people would want to listen to.

I wonder....
Well... if you've any suggestion, comments are always welcomed.
Enough musing for one night.
もう寝よ。
