Yeah it isn't, just didn't have any extra music to go there. -_-
I'm super indecisive about that kinda thing anyways. Like, should it be punchy and grab your attention immediately or be quiet/calm while the player peruses various options? (That sort of thing.)
Probably not; but the game I'm making next (a 'remake' of XYX, which was never finished) has a decent variety of ships to choose from - one of the new additions I'm planning is unique bomb types for each.
New content for FAX isn't out the question, though... I just need some distance from it first. Glad you enjoy it, btw. :)
