Missing Music

[Jenkin88]

So I have the HTC Inspire 4G, all of my music is downloaded through music apps however every once in a while my music will go missing and I have to re-download. Does anyone know the cause or how to stop this situation?

Um for some odd reason it mite be a cached music such as in Google music as they are in apps not directly to the SD card but if you hooked it to a computer and down loaded it to the SD card it should be gravy. And for some reason my phone used to not recognise the SD card all the time to make sure its all good go to your setting/l> storage<in mount SD card > then really mount it. DANGER DO NOT PRESS ERASE SD IT WILL ERASE EVERYTHING!!!
