I use my phone through bluetooth speakers, headphones and even my sound bars for casual listening. I play either my Sirius app or my mp3 files from my SD card. Lately, I have been getting weird noises that I can't really describe when I listen to the mp3 files. I replaced the phone, tried a different app, and every speaker I have. I think I've narrowed the problem to the card, hence my question. Can files on these little cards be corrupted?
