Personally, I think BF42 themes, although nice and all are quite funky given the gameplay
Even the theme for PHL seems functional for a tank battle, but I'm not sure it quite works in that context.
I once did suggest an overhaul of the main FH2 theme and default load music - Unlike BF42, it tends to lack character, no offense.
Its nice and all, but BF42's theme can be modified for each of the games in the franchise and it will still be recognizable... FH2's own is just rolling without personality or mood behind it
But this is just me
