Yea. Certain levels make the music drop for me. Only in the parts with the giant boulders you need to dodge.

Just beat the main story of Other M. The game starts off kinda iffy, but man does it get fantastic at the end.
And then it just stops.
Surprisingly good story, with a lot of fantastic twists, but it kept ramping up and ramping up, and then it ended. At least it's VERY heavily rooted in Metroid fiction. Even Metroid II is a heavy influence in the game. Hell, the manga (which was accepted as canon by the series creator) has it's role as well. And when a character actually speaks words like "Tourian", you know this game is serious about its continuity.

But the cool thing is that after the credits, Samus goes back and you're in control again, trying to recover something for an epilogue mission. So maybe THAT will have a better finale. It's awesome to start running through everything again totally powered up.
