The majority of script mods that tweak the common infected, don't tend to mess with any musical related CVARs, so you're good on that front!

Mods that tweak the delay between registered hits from the infected, typically by changing values related to the 'z_throttle_hit_interval' convars, could impact the results of this mod. However, from my own testing, mods that reduce the delay such as: No Delay Between Common Hits by ChimiChamo, should not cause any problems. Increasing the delay on the other hand, can potentially produce unintended results.

Music overhauls that intend to replace every track in the game, are guaranteed to conflict if they also have a substitute for 'mobrules.wav'.
