So I made a song about Pirates, Vikings and Knights II, a HL2 modification but as the song in fact uses nothing but samples from the mod I am not really allowed to upload it here. Anyway, I created a nice visualization video on YouTube so check it out if you're interested: http://www.youtube.com/watch?v=kpeVi57Qngo
But don't you worry. I am going to release another song soonish and it won't contain any copyrighted stuff so it will be released here. :)
