i usually use winamp to play my mp3s. but sometimes when i run winamp radio server i want to listen some other music with out opening new winamp or stoping server. so i play them with real play. but i dont have it in "open with" menu. so i go to open with and it's not there too, when i try to manually find path to it, it doesnt do anything. what's wrong with that thing and how can i fix it?
