DRM magement tool for the Rhapsody desktop client.It also seems to be needed to log into the client.I had deleted it,since it was "file not found" in an a Microsoft program I have (aotoruns).I then found myself unable to log in to the client.after a re-install a window advised me that a DRm component needed to be re-installed in order to play back unpurchased tracks.I assume streaming was meant,as the client downloads tracks to your temp file for playback at better bit rates.After doing this,I found MCSTRM had been reinstalled.This is all I know of this program.
