I've never used lsbox before, so this is off the top of my head. The .box file you have listed there will probably need to be made bigger. So, I'd first do something along the lines of changing the Height from 58 to about 78. That will give you a bigger box (heh heh heh - sorry, juvenile sense of humor :D). Then, add to the .box file
*ModuleHook !LabelLsBoxHook amptext
(amptext being whatever the name of the label is). Then, back in the file with the amptext settings (song.rc?) you'll need to adjust the x and y coords relative to the inside of the box. You may need to move the other elements down (adjust their Y coord in their respective files) if you want the amptext on the top. If you increase the box size by say 20, then the other elements would move down by 20 (add 20 to their Y coords), and the amptext would have a Y coord of 0... which would put it smack at the top. Just make sure to backup files before you start going nuts, and then don't be scared to experiment.
