drag blank folder icons onto stuffit expander icon-poof!!! it turns into an actual useable file the majority of the time. the only times i have not had this happen is if the file is unuseable in the first place. depending on what kind of preferences you have set, mp3 files may go to mac os cd player/mp3 player, but then it is only the work of a moment to move it to soundjam, audion, realplayer, etc. and leave it as a file in that application.
