I've starting adding new music tracks for my YR mod, and when I took a look at the thememd.ini file, I noticed the tag: Side=. Upon looking in DeeZire's guide, it said that the tag was left over from TS (I barely remember this function in TS.), and the code was left over but not actually used by Westwood for RA2.

Can someone please tell me if this tag is still a valid, usable tag. I tried using it to create a different track list for each of the three sides, but encounter much randomness with the result. For example, I have 2 tracks for Yuri only, but instead only Soviets get them. I have another track for Allies only that does not show up at all. And lastly, I have 2 tracks for the Soviets only, but one track was Soviet only for a couple of plays of skirmishes and has now suddenly appeared in Yuri's track list only when I play. The second Soviet only track is available for all three sides.

I read the Side= tag is based on the Sides list in rulesmd.ini so I'm using "GDI" for Allies, "Nod" for Soviet, and "ThirdSide" for Yuri.
