Right at this very moment I can't stop listening to Chaos Legion OST, this game has an amazing soundtrack despite getting average to bad reviews =-O .

Lost odyssey ost ..I would have sex with it if I could.....

But there's no sense crying over every mistake
You just keep on trying till you run out of cake!
And the science gets done and you make a neat gun
for the people who are still alive!

Yeah, for me it's Orange Box. Also, the "UR DEAD" song from Total Distortion.

The Darkness

The Darkness

And

The Darkness

I'm with Secondtooth on this one... Lost Odyssey is grand.

Pokemon

This week is Bastard!! OST

oh wait

Phoenix Wright

Yeah, im enjoying phoenix wright music at the moment.

Oblivion OST currently... though I wouldn't say I'm hooked... more like... too lazy to open itunes again.

Cookie I'm mainly listening to Phoenix Wright Orchestra music.

Apollo Justice - Start of a New trial and Phoenix Wright - Objection! mainly

Phoenix Wright Orchestra is really great... but in the moment it is the romeoxjuliet anime OST, which cant let me go... I listen it in the car, at home... it doesnt get old, no matter how often I hear it. IMO by far the best work of Sakimoto ever

Super Smash Bros Brawl

Amazing.

Finished the game this morning, btw =P

Time Hollow had me hooked for awhile now 3 weeks if not more. Good tunes.

now for those you guys suggested (except twewy I already listened the hell outta that one. deja' vu ftw !)

Metal Slug series(specially the 3)

Fate Stay Night (the anime and it's soundtrack)

Whisky

And Legaia Duel Saga's OST. Didn't much care for the game, but the soundtrack is excellent.

Namco X Capcom

This song.
