Do Metalheads Like Acoustic Guitar?  

That definitely sounds good to my ears. In fact I might be more likely to listen to the acoustic songs because they're more versatile. I can listen to them while working on something else easier than metal, which tends to take my attention.

Swallow the Sun - Songs from the North, disc II may answer the title question.

Personally I dont love acoustic guitar, but occasionally it can hit just the right way.
