As in the documentation for the Directsound object
, you need to use 'Play music' for MP3 files. Other actions only support PCM WAV files
. Secondly, the filename is "Title.mp3", not "Title". Finally, since 'Play music' rewinds to the beginning of the track and starts playing it, you will want to play the music on Start of layout
, otherwise you rewind and replay the track every time the screen draws!
