I've been asked to continuously play an mp3, even after the power goes out.  So I'm thinking I'd like to set up a cronjob to check on the mp3blaster process, if it isn't running, start one.  Also, the output is the soundcard.  So far I haven't been able to do it.

Any help would be appreciated :)
# $COMMAND is the command used to create the reverse ssh tunnel
COMMAND='mp3blaster -R myMP3file.mp3'

# Is the tunnel up?
CHECK_BLAST=`ps -eo args | grep "$COMMAND" | grep -v grep`

# If the program is not up, create the music!
if [ -z "$CHECK_BLAST" ] ; then
