There is not a single person on the planet who asked for a Carly Rae Jepsen/LMFAO collaboration, but remember, Carly Rae Jepsen isn't just the 26-going-on-16 blushing crushee of "Call Me Maybe," with triple citizenship in Canada, the Internet and your heart. In the music industry, she's just another developing artist and thus subject to featured-artist mix-and-match, which is how she ends up working with Owl City and now LMFAO.
In other words: we weren't looking for this, but now it's in our way: Jepsen and Redfoo wrote a song together. Over the phone, in fact; Jepsen ran into LMFAO's Redfoo at the airport--he's evidently easy to spot--an exchange not unlike the one in "Call Me Maybe" happened, and a song came of it, presumably for her record in September. (September seems rushed, but you can't exactly blame anyone for wanting the album out fast.) All well and inevitable, but Carly Rae Jepsen and LMFAO have... different strengths. Couldn't we just have a party rock remix of "Call Me Maybe"? Or a mashup, maybe? ...Oh well. There's always that Bieber collaboration.
