OB is the song played for when you are fighting the scorpion boss
Aseri2 is the song for battle arena.
OB and OA are essentially the same song. OA contains the music from the intro movie, and it also has the "bombing mission" theme afterwards. OB is the "bombing mission" theme alone. they actually didn't even need OA in the first place. SO don't bother assigning OA at all.
By the way, you're better off making your own list of files. It's really not all that hard, and it really reduces the stress level because you don't have to mold your file's names to the pre-set lists.
