Note that as DaveG mentioned earlier, $FmtPV must result in correct
PHP syntax.  Thus the quotes are necesssary, not optional:

>   $FmtPV['$SongTitle'] = "'".$songtitle."'";

(That is double-quote single-quote double-quote both prepended and
appended to your string.)

You do not need any other options to see {$SongTitle} on the current
page -- with what you have above you should be able to see the
variable (assuming quotes are corrected and assuming the order of the
rules is appropriate.)  I recommend getting your recipe to the point
where you can see this {$SongTitle} on the current page before
exploring other options related to caching the value or changing the
text or whatever...

(This probably goes without saying, but make sure you have a line in
your source on that page that says "The value of SongTitle is
{$SongTitle}" or something like that.)
