Warning! Spoilers for Harley Quinn #70 below

As the premiere of the Birds Of Prey film looms, Harley Quinn has revealed her music preferences in Harley Quinn #70, thanks to a karaoke song by a surprise guest superhero. Dr. Quinn has always emanated loopy musical energy, and her taste in tunes is, according to her self-narration, suitably unconventional. Of course, anything Harley says can be taken as a joke, killing or otherwise. But even as name-drops, the pop song allusions in this issue are illuminating and probably-intentionally hilarious.

From her origins in the animated Batman series to the Suicide Squad film, songs infuse Harley's story, with a slight bias towards sardonic breakup songs referencing her well-documented relationship with the Joker. She's crooned “Say That We’re Sweethearts Again," as made famous by 1940s film star Virginia O'Brien. In the animated feature Batman and Harley Quinn, she karaokes Blondie's "Hanging On The Telephone." At one point, she was in a folk duo with Poison Ivy.

In Harley Quinn #70, Harley wrestles, literally, with her new career in Los Angeles as half of a tag team with champion wrestler Alicia the Crusher. Harley diverts to a bar and hears someone singing karaoke to a familiar tune. Writer Steve Humphries, known for song-title references in his comics scribing, confirms that the lyrics of this fictive song are inspired by Meat Loaf's super-power ballad "For Crying Out Loud." The singer turns out to be Booster Gold, arguably the most Los Angeles of all metahumans, and obviously a karaoke veteran. In the DC discography, Harley knows this song, in fact, it's "her twelfth-favorite non-Enya song of all time."

For those not familiar, Enya is the Irish singer-songwriter who gained fame in the 80s and 90s with a new-age synth-folk often sung in Gaelic, notorious for its sparkling prettiness and frequent placement in epic movie trailers. Meat Loaf, among many things, is the guy who would do anything for love but would not do that. There is certainly some dramatic pop-musical thread that connects Enya to Meat Loaf's DC Universe analog (Meta Loaf?) which leads one to question, what are the eleven non-Enya songs that separate them in Harley's all-time favorite playlist?

Or possibly, she's just making a joke. Noteworthy, on an earlier page of this issue, Harley also sings a bit of Outkast's "Hey Ya," which is an utterly normal thing to do while shaking that which is like a Polaroid picture. Given the fast-and-loud themes on the Birds of Prey soundtrack, karaoke and comics aficionados alike may also enjoy the prospect of new insights into Harley Quinn's musical tastes, perhaps even a quiet moment of going with the Orinoco Flow.
