If you didn't believe our report that TechCrunch editor Michael Arrington is in bed with MySpace's top flack, Dani Dudeck, read the obsessive startup blogger's latest story on MySpace Music, which claims that MySpace has "streamed" 1 billion songs. Considering that most MySpace profiles are set to start playing a song, whether you like it or not, as soon as you visit them, that's not that impressive. Arrington leads his story by comparing MySpace streams to iTunes sales, and then acknowledges it's not a "fair comparison." His readers, in the comments, went much further, citing our report and questioning whether the affair with Dudeck clouded Arrington's judgment. Those comments have been — what's the word? — unpublished.

We know what TechCrunch's Michael Arrington got out of sleeping with MySpace PR executive Dani Dudeck: Screenshots of MySpace Music before the service launched. But what was Dudeck's quid to Arrington's quo? To find that, it's worth examining all the nice things Arrington has posted about her employer over the past couple of months.On MySpace's Data Availability, a feature which lets MySpace users link their profiles to other services like Twitter, versus Google's similar Friend Connect, he wrote:

When TechCrunch, the blog for startup fetishists, published leaked screengrabs of MySpace's just-launched music service, Michael Arrington wrote: "We’ve been pounding our sources for screenshots of the new service for weeks without any luck." Now we know what he meant. A tipster tells us, and another source confirms, that Arrington's been dating Dani Dudeck, MySpace's VP of global communications, for months.We're told Dudeck leaked Arrington not only the MySpace Music screenshots, but also tipped him to a story about MySpace friend-in-chief Tom Anderson's brush with the FBI as a hacker in the 1980s. The article served to burnish Anderson's rather questionable geek credentials. MySpace has helped Arrington's business in other ways besides feeding him stories. The News Corp.-owned social network was a major sponsor of the recent TechCrunch50 conference. Arrington has no issue bragging privately about his relationship with Dudeck. And Dudeck, our source says, has "no issues to sleeping with key influencers." Before Arrington, we hear, the rumor was Dudeck dated MySpace CEO Chris DeWolfe. But don't believe us — let's go to the tape. Check out this clip of DeWolfe and Dudeck together at the Sundance Film Festival earlier this year, caught by Kara Swisher for AllThingsD. The way Dudeck leans in to DeWolfe to stay warm tells you more than any of our anonymous sources. Kara's quippy response — "You don't have to love me" — reminds me of an anecdote my boss once related about Dudeck. The flirtatious MySpace flack accosted him at a conference last year and said, "We really need to work on our relationship." Sorry, Dani — Owen doesn't swing that way.
