(UPDATE 3) By Eliot Van Buskirk of Evolver.fm.

Facebook CEO Mark Zuckerberg announced 16 music partners on September 22nd ranging from almost-unheard-of to the incredibly popular. Of those, 7 have completed their integration with Facebook, meaning that they can automatically send users’ listening activity to their friends’ Facebook tickers and Music sections, and to their own Facebook Timelines. Here’s the full list in both categories:

We confirmed with Facebook spokeswoman Malorie Lucich today, with links to explainers on Evolver.fm:

Launched

• NEW: AudioVroom changes the social radio game.
• NEW: Deezer (review)
• NEW: Mixcloud ‘cloudcasts’ DJ sets to the iPhone.
• NEW: Rdio (review; family plan)

Announced

• SoundCloud, which is sort of like YouTube for audio, added record buttons to its apps and powers Outloud.fm among other apps. It was designed to “fix [one of] the web’s broken things.”
• TuneIn Radio is one of Evolver.fm’s top AirPlay-enabled apps.
• Turntable.fm, which took ‘social music’ past the buzzword, has received extensive coverage since then.
• Vevo, which hosts many of the major label videos on YouTube, is one big reason thatYouTube believes free music can pay as much as paid music.

That’s it for now.
