I put mp3 music on my sd card the regular way by dragging the songs in the sd card space on my computer. everything is fine until after I put them in, some mp3's turn into strange looking files. When this happens, the songs do not show up in my music player any longer. Also, when I try to play some songs that seem to not have been damaged, they play a track that is not even related to it. For example, I tried to play a nickleback song and it started playing zztop. I have looked and tried to pick out songs that looked corrupted or something but I can't find the problem. Now i do know that way back in the day I downloaded some songs off of a probably fishy website, but I can't tell which songs they were. Honestly, I don't know if my sd card is the problem or if its some songs that are the issue. I wonder, because I don't think a a few bad songs could corrupt half of my 2000 song library on my phone. It makes me think that its my sd card, but still I don't know. I have reformatted my sd card many times to try and fix this issue, but the same thing keeps happening. Help would be appreciated.
