Miami-based streaming music startup Senzari, which aims to take on Pandora by targeting the markets Pandora misses (i.e., the rest of the world), has just closed an additional round of funding totaling $1 million. The round includes investors in both Miami and Silicon Valley, including, notably Dave McClure’s 500 Startups.

The company had previously raised $2 million from undisclosed angels in Silicon Valley and Boston (mainly friends and family) and a private equity group in Southern California.

Senzari, the fourth startup from serial entrepreneur Bill Hajjar, offers an online music streaming radio service with a catalog of 11 million songs – a big jump over Pandora’s 900,000. As a radio service, Senzari is not trying to compete with startups like Spotify, Rdio or MOG, which let users program playlists and download tracks for offline listening. Instead, its value proposition is that it has a bigger database containing the “right” songs (meaning, the good ones), and, most importantly, that’s it’s available outside the U.S.

Also unlike on-demand services, Senzari doesn’t have to make deals with record labels to gain access to music – just distributers like SoundExchange, ASCAP, BMI and SESAC in the U.S., and others in different countries.

The company rolled out into beta in Spain back in February of this year in partnership with MTV, following its beta launches in the both U.S. and Brazil (where VH1 is its partner) in December 2011.

Another unique feature to the service is how it integrates social. Using Facebook’s Open Graph, Senzari aims to do for streaming music radio services what Spotify did for on-demand music services – that is, it will help you discover what your friends are into. Of course, Pandora offers some Facebook integration too, but Senzari plans to go further, not just showing you who listened to what, but combining data from both your own listening habits and those of your friends to serve up personalized music recommendations.

It also offers something called “Around Me,” which combines check-in data from Facebook to algorithmically suggest tunes based on what people at a particular location (like a bar, coffeeshop, etc.) tend to listen to. In other words, a social, local, Facebook-based radio service.

The new funding will be officially announced tonight as the Geeks on a Plane (#GOAP) Latin American Tour kicks off in Miami. The 10-day tour includes stops in Mexico City, Sao Paulo and Buenos Aires.

“We are excited about joining the 500 family as it allows us to leverage its impressive mentor network and global relationships,” says Senzari COO Demian Bellumio. “As a matter of fact, we created a special section in Senzari with radios for each of the stops of the tour with music that represent current and classic hits.”

The company plans to use the funding to expand its core team, strengthen and add features to its service, and continue its rollout to other regions. Although Senzari won’t reveal its expansion goals right now, the company will announce more countries and partnerships in June at the LeWeb Conference in London.

Ever since I met the Songza guys at New York Tech Meetup, I’ve wanted to learn more about the app. It’s the first music service that I’ve been excited to use, mostly because it removes the work entirely. I’ve been curious about a few things, like how Songza plans to combat the big boys, namely Pandora, and how exactly these guys are making any money. Remember, Songza has no audio ads, no limits, and is free to download.

Co-founders Elias Roman and Eric Davich sat down with me to discuss this and more, saying that the only way to enter into a space as crowded as streaming music is to bring something totally different to the table. They said that they see a really big gap between music subscription services and radio services, in that using a Spotify can be hard for some people and Pandora can get stale. What Songza does is eliminate the mental math of figuring out exactly what you want to listen to.

But the possibilities extend far beyond that. Songza is collecting tons of data on the way we listen to music and what we’re doing when we choose a particular genre or playlist. Since Concierge is meant to get smarter the longer you use the feature, this data should be invaluable in fine-tuning the app even more.

It took a little while, but Digg finally has a new head of PR. The company has hired Michele Husak, who previously held the same job at Pandora, the streaming music recommendation engine. According to her LinkedIn profile, she started the job last month, but they’re just announcing it now.

Husak takes the official title of Director of PR, which is the same position vacated in November by Kiersten Hollars, when she stepped down as Digg’s Director of Communications. Hollars left Digg to re-join her former boss, Brad Garlinghouse who is now helping to re-build AOL. Hollars and Garlinghouse both left Yahoo around the same time in 2008, which is when she went to Digg.

Aside from Pandora, where she has been for almost four years, Husak has worked for Shopping.com  as well as Jupiter Research. She also experience handling various roles in different areas of entertainment, apparently. Digg has recently been doing more video work with its Digg Dialoggs, which are interviews with various prominent people in different industries. It also appears to have trademarked the name DiggTV late last year, which currently is an area of the site that houses all their videos. Regardless of that, the company will be in definite need of some PR guidance soon as they gear up to launch a more realtime experience for the site.

Husak may need a bit of time to get up and running with Digg, it looks like she signed up for the service just prior to landing her new gig.

Online music services have had a bad few weeks. Imeem got bought by MySpace for next to nothing, Lala got bought by Apple for something ranging from a little to not-very-much. Spotify continues to be a no-show in the U.S. But at least one service, Pandora, appears to be doing quite well for itself.

The service has announced that it surpassed 40 million registered users earlier this month. That means the service had doubled its size in 2009. And it’s adding 600,000 new registered users a week now. Even more remarkable is that half of those new users are coming from mobile devices. And of those, the iPhone continues to lead the way with 10 million Pandora users of its own. That number has grown some 400% this year.

These good numbers follow the news earlier this year that Pandora had officially been “saved” after reaching an acceptable deal with the music companies for the royalty rates they have to pay. Pandora, unlike the other music services mentioned above, is much more of a radio service in the traditional sense of the word because you can’t pick exactly which song you’re going to listen to. But a proposed rate hike, which almost went into effect, would have severely hampered Pandora’s ability to survive as a business. Instead, with the new deal, they expect to be profitable by next year.

And that certainly seems possible given that Pandora is now apparently accounting for 44% of all Internet radio listening hours, Ando Domestic Ranker and their own internal numbers confirm. And they have great demographics to serve up ads to. Amongst 18-24 year-olds, Pandora has twice as many daily visitors as Hulu and ESPN, according to comScore. That said, the more music Pandora streams, the more they have to pay, so they need those ads to be effective. But that seems to be the case.

And while you might think the surge in mobile usage might be bad for Pandora which relies heavily on the ads that blanket its website, number indicate they have been able to monetize these mobile users as well.
