I tried looking up how to make this mod myself but failed to do so. I'm now requesting one of the talented modders to bring this dream to life. Saints Row 2 has some incredible songs, but this one, Gangsta Bitch by Apache, is the highlight of the menu music.

I know someone has the talents to do it. I would really appreciate it.
