Hi, I really like this track, its awesome, i love it...
...and I have decided to use it in my game (free game, probably).
This track (2014-10-30) has been licensed http://creativecommons.org/licenses/by/3.0/ which states:

I write this just to make sure that nobody is going to be hurt - but technically it seems, that this tune can be use for free (as long as credited) (Jamendo says that for commercial purposes I need to pay around 100 euros, but this is against license itself).
