This is the first time im making a beatmap and i wanted to this song because it's catchy and i cant find one of this song. However, Im having trouble with setting up the bpm. For the first few seconds it's ok but then a minute later its completely messed up. 
I REALLY want to make a beatmap for this so can anyone help me? Plz~~~? If any one has some extra tips you can offer that would also be helpful! I'd really really appreciate it if someone answers this so thanks! 
The song is "Musunde Hiraite Rasetsu to Mukuro" here's the link: http://www.youtube.com/watch?v=syTLWDx25io
