I created Satin so I can certainly answer that.

The song info is on a line of alternating text. You just need to change the amount of time the line is displayed, so your complete title is scrolled before the line alternates.
So change this line...
%?C<%s%t5%al%?ia<%ia|> - %?it<%it|>|>;%?C<%s%t5%alAlbum: %?id<%id|%d1>|>;%?C<%s%t5%al%?ia<%ia|%fm> - %?it<%it|%d2>|>;%?C<%s%t5%ar%?Ia
|>
to this...
%?C<%s%t10%al%?ia<%ia|> - %?it<%it|>|>;%?C<%s%t5%alAlbum: %?id<%id|%d1>|>;%?C<%s%t10%al%?ia<%ia|%fm> - %?it<%it|%d2>|>;%?C<%s%t10%ar%?Ia|>
...and that should do it. Or just tweak as you like.
