media player playing wrong track!

I upgraded my 9900 to 7.1 and the media player is acting up now. Basically, it is playing the wrong track / is out of sync! If I select the first or last song of an album, that song will not play at all. If I select any other song on the album, the media player will actually play the previous song but still show the album art and title of the song that I selected. It is a joke! This is not a rare occurance, it has happened at least once a day for the last week, since I upgraded to 7.1. A battery pull fixes the problem for a while.

Anybody else seeing this?

I've got the same problem. currently wiping all the music off the phone to see if that will help.
