I have a Zenithink ZT-180 Tablet running Android 2.1 with a 8GB MicroSD card. My device won't recognize any MP3 files I copy over. I left 1 MP3 in the root folder as well as /Music (capital M and small m). I copied a TV show over to the SD card and RealPlayer picked that up right away. Any insight as to why the device does not recognize any MP3s?
