I hopped in the time machine and dove back into the early 2000's to compile a playlist of songs that could have potentially made it to Smackdown SYM/HCTP's soundtracks had they had real songs in the game at the time and not just instrumental tracks,  most of the songs featured are from 2000-2003. This replaces all menu music.
Instructions 
Simply paste the game_mode_m.pck file provided into your WWE 2K19 sound folder and replace. Be sure to make a backup of your original .pck file before replacing just incase any issues should arise!
