Credits to the forums over at Shoryuken for posting the video for the opening.

This is the song that plays at the beginning called The Next Door, also known as Indestructible. Its the full Japanese Version, and while its not the best quality, its decent.

I don't have the English version, but I'm sure it'll be on the SFIV soundtrack that comes with the Collector's Edition. Anywho Enjoy!

This one has better Quality (Japanese Version)
