Anyone have this issue and know of a fix? I've formatted my sd card and moved music from pc to card twice now. Each time, only 4 or 5 of the hundred or so songs will actually play on my s2. I've tried using Apollo and PlayerPro, as well as another app or two. I get a "this file type isn't supported" sort of thing. I never had an issue with a 16gb sd card I used, but this one is 32gb. Not even sure that would be part of the issue. Any tips?
