Ok, so there are two tunes in this 375KB package:
pocket.it -> "Pocket Tanks (intro)"
ingame.it -> "Pocket Tanks (ingame)"
The first one can be described as "cute", nothing more.
But the second one seems very quality made.
By "very quality made" I mean that the samples
are HQ and there are over 42 channels used!!
The style is serious and it seems like it is from some movie. But don't get me wrong, it IS melodic.
I recommend you to add this package to your mod collection.
