It’s been said that Microsoft could be most likely blocking the introduction of an official Grooveshark client for Windows Phone. In accordance with a conversation between the community developer and a consumer, it’s claimed that the Grooveshark team had formerly looked at getting an application listed in the store, but were informed by Microsoft that this kind of an app wouldn’t be approved.

Therefore is this the end-all for Grooveshark fans? There was an unofficial Grooveshark application in the works for Windows Phone Store, however, there is also an official solution on the Grooveshark web site, utilising HTML5. Although not a native application, it’s certainly worth checking out if you’re an avid fan of the program. That said, Microsoft does provide its own Xbox Music service, which provides unlimited streaming and offline playback for a small monthly fee.

Grooveshark has encountered some issues with music companies in the past relating to royalties and maybe that is playing a role here. Or it might be Grooveshark deflecting blame, mistakenly, to Microsoft. In that case, maybe Microsoft’s great developer support could reach out and rekindle that conversation with the Grooveshark folks.

Nevertheless, third party submissions of Grooveshark customers to the Windows Phone Store happen to be blocked previously, therefore there may be some reality to this report. Furthermore, the third-party application referenced above by SciLor hasn’t had its private beta up-to-date because the beginning of April, and even then it failed too well, making us little hope for that project.
