Wow... Why didn't I notice that in the first place. Done, I deleted all on the list but the obvious ones for fights. Oh and I found a way to edit music for like the beginning bombing mission, so you don't have to listen to the intro. I went to a site called http://mytinyphone.com
It's meant for editing songs to make into ringtones... But it works just the same. You can cut out parts of a song or select where you want the song to begin. SO I just made it play after the intro. Then just save the file it makes to your computer. I believe it's in MP3 format.
Not sure if that helps for anything. But just thought I would share a discovery of mine.
Thank you, Obesebear, for pointing that out to me, about the option. Not sure how I missed that one.
