OK, but1) It can't be usable until there's engine support for correct acm headers.
Existed 1pp HQ music mod already add 44Khz acm support (by bad way), if engine gets dynamic 22/44 acm support, it lost compatibility with this mod. Currently no other 44khz music mods(?), so compatibilty with existed mod is high priority.
2) 1pp music package does not install content. It has to be copied manually, and there's no uninstaller for that. Do you consider it not a real mod, then?
For me, it is not real mod, we don't live in 1999, we have weidu "standarts", players used to have install/uninstall option, mix MODs combination etc.
