I've just recently moved from a iphone 3gs to a RAZR M and love the switch. The problem that I have is that I copied a heap of mp3 files to an external 32gb micro sd card that I inserted. When I go to play these files in a few music players like google music, winamp etc.. It doesn't seem to have indexed all of them, what I mean I is I can see all the songs listed but I press next or choose a song to player it keeps playing the same one or the song that plays is not matching to the one that is listed ? Any ideas what this could be ?
