People from Sweden and English Language

My native language is Dutch, so I don't know if it's the same principle, but when something is sung in Dutch, it just sounds ridiculous, while if the same lyrics are sung in english, they sound good o_O
 
shit yo, i wrote a letter to my sweedish cousin, even got it translated by this sweedish chick and she never wrote back, what a total bitch, i might give some of you crazy coo-coo sweeds her address so you can mess her up nice-like

PS: checked out nightingale tonight, good stuff.
 
Obviously singing in English for a band that's from a small country is helpful to reach a broader audience. I don't think Opeth would be too recognized here in the US if they sang in pure Swedish?
Makes sense to sing in English to get some fans.
