Hey Cid
You don't even need to do that as a workaround- by going in the playlist you can probably just take away any battle songs (just make sure you back it up)

Weebeast, I realized it does look like an RTW playlist (I don't have RTW though, so I'm not sure....) it's from a mod I have been making for a long time based off of HTW.
I think the custom lists are the extras..... it says you can have six songs for each slot for each grouping of songs, but I have found that it doesn't work unless you use five; however, I will test it again some time.
Thanks!
Justin
