BREW平台下，怎么让背景音乐循环播放？

/*  Music Play */
if(SUCCESS != ISHELL_CreateInstance(pMe->a.m_pIShell,AEECLSID_MEDIAUTIL,(void **)&pMe->plMediaUtil) )
return FALSE;

pMe->date.clsData = MMD_FILE_NAME;
pMe->date.pData = "back.mid";
pMe->date.dwSize = 0;
if(SUCCESS != IMEDIAUTIL_CreateMedia(pMe->plMediaUtil,&pMe->date,&pMe->pIMedia) )
return FALSE;

IMEDIA_SetMediaData(pMe->pIMedia,&pMe->date);
IMEDIA_Play(pMe->pIMedia);   
/*  Music Play */

这里音乐只播放一次就停了，怎么让循环播放？
[解决办法]
注册回调，在回调中检测音乐结束的事件，然后再重启音乐播放

检测状态，好像是。。MM_STATUS_DONE
