Trying to add/change music tracks to KOF97

Hi, everyone
I've been trying to change some music tracks in kof97 in order to get rid of the ambient tracks and include music tracks from kof98 psx or neoCD instead. Since the game uses redbook audio tracks I tried simply replacing the tracks with others from kof98. I cut these to the same length in time using audacity and renamed them as in the cue file. The image I built with the tracks changed worked ok in SSF emu but when I burned it to a CD and tried in my console the game worked but without music at all.
What should I look into to make this work on real hardware? Huge thanks in advance!!
