Only last one sounds like real chetnik song..first one i never heard of and it seems like new patriotic song..third one talks about a war hero Mauzer and his Panthers...he was killed by the criminals after the war..only ten years later his killers were convicted ..probably they stepped on someone's toe from political establishment..
Your Serbian is perfect..keep up..
Thanks
By the way, who's "Alija"? I didn't understand that reference – "Ој Алија, ниси више главни" (Oj Alija, nisi više glavni/Oy Alija, you're no longer a Major), is that a reference to the Islamic pig Alija Izetbegović?
