I like the default music, don't get me wrong. I think however that the battle tracks get a bit old over time as the one you will hear most of the time is the human one as most custom races use TA as a template due to how the "create custom race" button works.
I was wondering if someone knew how to make a music mod. I saw one release but that mod is old and no longer seems to work. Preferably, I would like one that can randomly pick tracks so no music in the game needs to be scrapped as there are instead multiple ones playing during the same situation.
