European streaming music service Spotify plans to launch its U.S.-based service in the third quarter, according to details shared in a recent interview.

Senior VP Paul Brown made the statement to Bloomberg in an interview, where he reiterated the company's ongoing efforts to secure server space here in the States, and that label licensing deals have yet to be completed.

Not much else is new. Brown reiterated Spotify's discussions with Research in Motion and Palm to bring its mobile application to their smartphones. Spotify already has an iPhone and Android app.

And rumors continue over some type of potential deal with Google. Details remain slim, but sources tell that the two companies have been in ongoing talks for several months. Those rumors led to a belief that the Spotify service would find its way onto the Nexus One Android device, but that never happened.

While a firm date for Spotify's launch is something anyone following the digital music market has long sought, other important questions remain. Of particular interest is what the service will look like here in the States. In Europe, Spotify has attracted a large following by offering ad-supported, free on-demand streaming, with a migration path to a monthly paid premium service.

But labels here in the U.S., particularly Warner Music Group, have expressed disappointment in that model and are not likely to license their music for such use domestically. That has many expecting Spotify to have no choice but to launch as a monthly paid subscription service with a far more limited free tier than that experienced overseas.

Meanwhile, as the company works out these issues, competitors such as MOG and Rhapsody are digging in, and all eyes remain on Apple's plans for a cloud-based music service.
