Thanks a lot!

This is "The anthem of riots from Panagiurishte". The bulgarians used to sing it in 19century while fighting turks, it was about to come our anthem a lot of times. /I hope it will someday/. This one they play in the hall is remix, as national song played at national holidays it sounds like this http://www.youtube.com/watch?v=7XgyPAsb5Vo .

the song calls "we suck and we know it", you can find it pretty much in all bulgaria games.
