As music streaming service Spotify debuts in the US, here’s a brief look at the internet radio audience.

eMarketer estimates 37.5% of US internet users ages 12 and up will listen to internet radio—including online streaming of terrestrial broadcasts and online-only radio stations—or podcasts at least weekly this year. On a monthly basis, 44.3% of web users will tune in to online radio.

“It’s a positive and long-overdue development for the U.S. recording industry, with favorable repercussions for brand marketers and consumers,” Paul Verna, eMarketer senior analyst, told the E-Commerce Times. “Spotify has a good chance of succeeding in the U.S., but to do so, it will have to demonstrate — through the quality of its product and aggressive marketing — that it’s a better value than the likes of Rhapsody, Rdio and MOG.”

Could there be a Facebook and Spotify partnership in the making?

“If the two parties work well together and their current test evolves into a true partnership, Facebook could do for music consumption what it did for social gaming,” suggested Verna. “This relationship has the potential to blossom into a symbiosis along the lines of what we saw with Facebook and Zynga.”

A complete report, “The Internet Radio Audience: Personalized, Mobile and Targetable,” is available for eMarketer Total Access clients.

The rapid rise in popularity of social networking sites as a venue for casual gaming since Zynga released FarmVille in June 2009 will drive overall US social gaming revenues to $1.09 billion this year, eMarketer estimates, up from $856 billion in 2010.

Nearly 62 million US internet users, or 27% of the online audience, will play at least one game on a social network monthly this year, up from 53 million in 2010.

Revenues from virtual goods make up the majority of overall social gaming revenues, accounting for $510 million in revenues in 2010. eMarketer estimates social gaming sites will earn $653 million in virtual goods revenues this year, compared to just $192 million in ad revenues and $248 million in lead-generation offers.
