If you're still in the market for a mobile music subscription service and happen to use a Nokia Lumia, that company has something for you. Today, Nokia announced its Nokia Music+ service—a freemium-style upgrade to its current mobile music offerings with features such as higher quality music files and desktop compatibility.

Nokia was quick to note that Music+ is an additional experience and not a replacement, and that those who enjoy Nokia's current free service can continue doing so. “This is for people who care enough about music to pay something for more quality and choice, but don’t want to pay €9.99 monthly,” Jyrki Rosenberg, VP Entertainment at Nokia, told the Nokia Conversations blog.

Nokia Music+ will debut in the next few weeks and the price is expected to be around €3.99/$3.99 per month (cost will vary slightly depending on territory, according to the introductory post). What exactly does that fee bring? Users will have unlimited skips with Nokia's Mix Radio service and unlimited downloads of its Mixes for offline use. As noted above, the music files will be higher quality (the blog states you can "download music at eight times the existing quality") and the service will be available for desktop use through a Web app. On top of all that, Music+ will encourage your cover band dreams with a new Lyrics feature, which displays your sing-a-long data either in an auto-scrolling list, Karaoke-style format, or navigate-on-your-own scrollable display.

With a crowded mobile music market—Spotify, Rdio, Rhapsody, MOG, etc.—there's no telling what the demand will be for a pay-upgrade to an already niche service. But keep an eye on your Nokia Music interface; new options will be springing up soon regardless.
