Wow, can't believe I fell for it. Decause i am in Finland and English is not my original language and first time i didn't get that and i read that again and then i cet and realized that i am really an idiot xD xD
update: I tried with all my songs and yes I know it doesn't work with every song. I just think it works if you play the song on time or it works with some sort of upbeat song. But yea, it doesn't work perfectly like you would expect.
