it's just the chorus(not very similar about 60% notes), not the whole song , if it's the whole song, then is called rip-off,but it's NOT, actually, it doesen't really matter, many songs' some part is simaliar to other songs
i always don't understand why you guys say stupid thing like this
ONLY 60% NOTES ARE THE SAME(you can count that, i don't think it is VERY similar !)
