Why is my SD card not showing anything

I have a LG G3 and all day today my music was on my phone and now my SD isn't mounted and won't show up on the phone and my music is gone.

Have you tried removing the SD Card and re-inserting it. You can also try placing it in another device to see if the data is there.
