Yeah, it must either be a setting on your phone (look under options, either general icon, or in the media player) or your OS is funky, in which case you need to reload it. The only other possibility is the songs are messed up (unlikely if they play on your DAP) or the card is messed up (unlikely since you can load it and the folders format). Sorry but you've got more work to do!
