Stop currently playing music

[LudiusMaximus]

My goal is to start my own music in certain situations. E.g.:

PlaySoundFile("Sound\\Music\\ZoneMusic\\UlduarRaidInt\\UR_TitanOrchestraIntro.mp3", "Music")

But I obviously do not want the new music to play on top of the currently played game music but to temporarily replace it. Then, when my custom music piece is over I would like the standard music loop of the game to carry on.

Is it possible?
