A few Question

[abundantclearly]

I don't think any music Modder has been able to make the music wrap-around or play all the tracks they add.
You can't make Tribes of the east work smoothly on a computer with 512 ram , the min, is 1 GB but 2 is recommended.

You can look for and install music mods for Heroes V 1.6 and Tribes of the East if you'd like to hear more organic and varied music. These mods can update and add in-game background music, giving additional diversity and richness to your audio experience. Turn off superfluous apps: Before launching the game, make sure your computer is free of any background programs that aren't necessary. This enhances gaming performance and frees up system resources.
