The pipe syntax is usually provided by the shell, so you can probably get it 
to work by calling /bin/sh directly and giving your little script as argument 
to the -c option:

/bin/bash -c 'grep Title /tmp/xmms-info | gawk ... |'

Need to be carefull about single tics inside the command, and keep in mind 
that a shell invocation can slow things down quite a bit, depending on the 
config files it has to parse (~/.bashrc, .profile and the like)
