Sweden. It's all fucking Sweden's fault.

Today's Retro Jam comes out of 1977 and stars the Swedish sensation that you either love or love-to-hate.

Resisting the Lucas-esque compulsion to digitally swap Pierce Brosnan's open-throated squawk with a mellifluous gay lilt, Universal has instead touched on a decidedly more modest touch in tweaking its hit Mamma Mia! for a late-summer revival: Subtitles, and plenty of them. Behold Mamma Mia! The Sing-Along Version, announced earlier this month and finally making its way into karaoke-plexes near you this weekend. And the early reviews describe just the scenario that can make the ABBA musical a phenomenon all over again:

Are you sooo super jazzed to see Mamma Mia!, that Meryl Streep movie musical based on the Broadway show which is built, in ramshackle fashion, around a raft of ABBA songs? If you are you just might be a gay person. And we love you for it! But you know who wouldn't love you for it? Hitler. And you know who has ties to his Nazi party? Beebop band ABBA's own Frida Lyngstad. Time and circumstance came to reveal that she is the daughter of a Nazi officer who, along with many others, was spreading his seed around Norway in the hopes of creating a master race. Like this was an actual eugenics plan commissioned by Berlin. A new documentary on The Jewish Channel chronicles the story, a preview for which (via Radosh) is after the jump.

In a research breakthrough that will solve ongoing arguments across the world, an Australian website has tallied thousands of votes and put together a definitive list of the gayest songs of all time [via Queerty]. The full list is 50 songs deep, and can be seen here. But because our motto is "Servicey in gay music matters," we've got the top ten list—and a video of the GAYEST SONG OF ALL TIME—after the jump. If you're an ABBA fan, you have something special to look forward to.
