Today we reported about the mysterious "Music Player Demo" appeared on Sony Computer Entertainment Worldwide Studio President Shuhei Yoshida's PSN profile, and looks like there's more to that app than meets the eye.

A tipster that opted to remain anonymous spotted VP of Publisher & Developer Relations Adam Boyes (who is on his friend list) while he was actually using the app, and it included the option to join the session. When he tried, he was notified that he couldn't join because he didn't have the app himself, but he was also told that Boyes was enjoying it with another user, also displaying that user's name.

If the app really is a music player (as also hinted by industry insider Tidux, who has already demonstrated to be privy on what happens at Sony), this could indicate the ability to listen to music with your friends on the PSN, which would definitely be interesting.

Of course we should consider this a rumor until confirmed by Sony Computer Entertainment itself, but I can't say that the perspective isn't  intriguing.
