Just a caveman music (midi and xm)

I've made a music a bit time ago, and I call it the "Caveman" music. You may use it where ever you want, not even credits is needed. This music may also be used for GE examples, such as the plratformer with caveman. The music is avaible as midi and xm, there's one looping music and a song, that can be used at the end.
The music has got a length of 42 seconds.
Here is the zip file containing four files (2 MIDIs and 2 XMs):
