Flavorwire has done some personality deconstructions based on which love songs you like.  Yes, it's stereotyping, but that's the point.  Here are some examples.

If you like Joy Division's "Love Will Tear Us Apart," then "That pallid college friend who you should probably call casually to check on right about now."

If Elvis Costello's "I Want You" turns you on, chances are you're a man "subject to restraining orders in at least three states."

If you love "Lovesong" by The Cure, you are probably an "ex-goth who [is] perfectly okay being described as 'unashamed romantics.'"

If your favourite long song is "Closer" by Nine Inch Nails, then chances are you're a "black-clad type who may or may not be an actual vampire."

And if you think "Every Breath You Take" by the Police is an awesome long song, you belong to a group of "clueless Diddy fans who don’t listen to the lyrics properly."
