Pros:

- The 13  campaigns have their own theme, pretty well chosen to fit the atmosphere of each one. Particularly, the sacrifice has the best song that could be chosen for it, never heard something like that before.
- The tracks are good chosen overall, there is no annoying themes too loud or too fast in speed to distract the attention from the game. Also each theme fits its purpose, theres no random music.
- Inminent Horde themes.

Cons:

- There are problems with loops, neither the tank or the skinonourteeth are looped, the tank music restarts in a very shocking way, and the skinonourteeth ends like 10 seconds before it is programmed, so theres a moment without music before it is played again. But they are very difficult to loop without being only drums.
- The main menu music is awesome but its volume is too low.
- yourownfuneral ends very abruptly in my opinion.

Conclusion:

Very well made overall, a hard work, with some problems with the loops. For the skinonourteeth track, if you edit the new music so the length is the same as the original track, it should work nice since the loop doesn't start from the beginning of the song like the tank music, it respawns somewhere in the middle.
Check out the "Battle: Los Angeles" soundtrack, it has many good songs that you could use for future works.
