This really bugs me. There's a movement in advertising to take downbeat, slower, depressing or eerie versions of more upbeat tunes and use them as mood music for perfumes and movie trailers. Now, I wouldn't say any one of them is awful (they're not that good, though), but en masse as a movement, it's downright obnoxious. Especially since they're all moaned out by the same sounding female vocalists that sound like they've recorded these after getting an unexpected wrong number phonecall at 3 AM. Think that cover of "My Humps" with all the satire and irony drained out.
Examples? The oh so romantic sounding "Addicted to Love" for some sort of fragrance. Calvin Kline maybe? Something that's faux-artistic and pretentious, but the really bad kind of pretentious that doesn't even know how to do pretentious right. Then there's one for a Liam Neeson film that uses a slowed down, moany version of "One way or Another." OH! I get it! Because if it sounds ominous, the lyrics can be reinterpreted as serial killer-y! AH! I wouldn't have got the heavy handed, obvious imagery of the film had the lame music not pointed it out. I swear there's like one or two more. There's the really bad "Crazy in Love" they used for the commercials for the trailers for "Twilight with the names swapped out and NOT researched bondage thrown in." I'd say that started off the trend, but the minor key variant of "Once Upon a Dream" from Maleficent kinda did. It just wasn't surrounded by poor imitations.
Also of note, there's this commercial for a video game that uses "Ready or not, Here I Come, You Can't Hide" (or whatever it's called, it goes like that), slowed down, but sung by a choir of little British boys. And I got to admit, it's a nice touch, the original song sucked anyway, but it's very freaking Squicky considering a choir of young boys is singing it. Like Michael Bluth and Maebe singing "Afternoon Delight," but with very unfortunate implications that they're a CHOIR of YOUNG BOYS.
