The day before yesterday I ran into this error: Error: Error #2037: Function call sequence is incorrect, or a previous call was unsuccessful. at flash.media::Sound/_load() at flash.media::Sound/load() at org.mousebomb.media.musicPlayerV4::Mp3Container/loadMp3() at org.mousebomb.media.musicPlayerV4::Mp3Container/nextMp3() at org.mousebomb.media.musicPlayerV4::MusicPlayer/aC()

After looking into it, the cause of this error is: a Sound object only allows one sound stream to be loaded onto it; even after calling close(), you still can’t load another sound onto it. Once load() has been called on a given Sound object, you cannot load another sound file into that Sound object. To load another sound file, create a new Sound object.
