Minor correction - try
echo DISPLAY=$DISPLAY noatun my.mp3 | at 1621

You need the DISPLAY environment variable to allow noatun to display
on your logged on X session. Of course, if you log off before noatun
runs at 1621, you won't own the display that the DISPLAY variable
points to, and noatun will crash with that "Error: Can't open display"
message
