I downloaded Gtunes music downloader today and started downloading music. out of 30 songs none of them worked properly, either choppy or just didnt work while playing them through the gtunes music player. they also did the same thing in the phones music player. so i moved them all to my SD card, reset my phone, and when trying to play them again to see if the issue was fixed, none of them work now. other songs that i have downloaded with other mp3 downloaders in the past still play just fine, but the ones i downloaded today dont play at all and gives me a message saying "unable to play this type of audio file" any suggestions on how to fix this would be GREATLY appreciated. would like to listen to my music..
