Absolutely yes on the creepy song lyrics! I'm not familiar with the one you cite, but there are plenty of other "love" songs out there that are needy and obsessive, at the least. I don't imagine the lyricists meant them to be creepy...but they sure can sound that way.

And some things get misread as love songs, that were never intended as such--I remember hearing an interview with Sting back in the 80s, in which he said he really found it disturbing that so many people seemed to think "Every Breath You Take" was romantic.
