Need help with extracting music from Saints Row 2 (PC version)

The other day I was trying my luck with the PC version of Saints Row 2. I’m no tech noob, but even so I didn’t manage to get the extracted files to work.

I tried every tool out there – and I mean really every one – and I did managed to extract wav files, as well as xna files. But even after two days of intensive Google research and trial & error I can’t get these files to work. The best I got was the pause menu jingle and four tracks, and that’s it.

Could someone who converted the files successfully in the past or is otherwise an expert on the matter please tell me how to do it?

I wish you all the luck, I’ve been dying for a proper rip of SR2 for years.
