Here's a link to the full 2 hour soundtrack. When playing the game I kind of dismissed the soundtrack. There was a few good bits I could remember when thinking back on the game but they were few and far between. Quite forgettable really.
Then I listened to the soundtrack linked below. 1st time through I was, "that's a cool track....ah that's that level with this boss...yeah there's a few good tracks".
2nd time through I was "ah this tune is bangin' and this one...and this one."
Now I have it on in the arcade every time I go in there and chill, play, fix etc.
It's a grower, but once it gets you, it gets you.
