Yeah, I have these images grouped into three categories and it is divided on the website, but I can't implement the division into foobar. In other words, I can't make one set apply only to specified genres and, and likewise with the others. Tried $if functions but nothing comes out of this. If I don't find a way to make it, I may stick to the unofficial scale.
You may be able to get it working using something like this:
$if($and(%album dynamic range%,$or($stricmp(%genre%,classical),$stricmp(%genre%,soundtrack))),$imageabs(x,y,w,h,skins\dynamicrange\HIGH\DR%album dynamic range%.png),)
$if($and(%album dynamic range%,($or($stricmp(%genre%,alternative),$stricmp(%genre%,pop),$stricmp(%genre%,rock))),$imageabs(x,y,w,h,skins\dynamicrange\LOW\DR%album dynamic range%.png),)
You should then be able to use the $or function to specify more genres. If anyone has a more elegant solution, then please feel free to suggest.
