How do you add ur own arena music?????

I've replaced the front end music and pause menu with my own music...but does anyone know how to replace the arena music (the music that plays when your playing)....doean anyone know??? Any info will be appreciated.....

this is thet old-school method, but use the ditty importer for NHL 2001 (i think it was 2001)... not sure if it can be used anymore

i dont think its possible with the ditty importer
the arena music is in a diffrent format than the ditties
