A lot of Nickelback's songs give me this strange feelling, so it's hard to point out one, but this one puts me in that weird mood, it's not that much about melody, more of text itself.
The Black Dahila Murder - "Moonlight Equilibrium"
And a lot of other metal artists put me in the mood of decyphering the text (lyrics) and learning about the artists wisdom, for example this particular song says the following: Basicly how I'd put it, is the artist sings about how a lot of people think that they have to kill someone in order to gain something they wish, but of course not like literaly killing someone but for example the way a lot of doctors let people die in order to get money, but they don't care about said people. (I'm not saying all doc's are like this, no offense meant if someone here is a doctor).
