I contacted the artists Mad Mav and he replied me positively, here is his agreement :
thx for your interest. Of course you can use some of my songs. The only condition was, that the users of your game do easily notice that I am the composer of the song, so that there is also some kind of promotion for me.
Wich songs do you want to include in your game? In what kind of file format do you need them?
There are a lot of songs so good luck to choose, but please don't choose more than 3 or 4 songs.
