AC Question

No music shown in MP3-player from SD

Hello all,

Today I was transferring some new music from my pc to my SD card (sandisk 16GB).
When I was done, I disconnected the SD from my pc and put it back in my phone (Samsung Galaxy Express).
But when I went back to my MP3-player no music was showing, this was quite strange, but I let it go for an hour or so.
After an hour still no music displaying, the only way of listening to my music would be to go to "My files > all files > extSdCard > Music''
I have tried all I can do, but still no music displaying, these are all methods I've tried from googling:
-Format SD card and put the music back on
-Unmount SD, mount back in, clear cache of MP3-player, restart phone
-Connected phone to pc and looking for .nomedia files, nothing found.

At this point I don´t know anymore, any ideas?
Thanks in advance!
