Phone doesn't properly recognize files on my SD card?

[pogiako123]

Hi, I own a lumia 520, and I got a new sd card yesterday. My old sd card was properly recognized by my phone. But as of today, my new sd card doesn't recognize the files properly, all of my music files were on the "others" panel at the storage sense. I hard reset my phone before using my new sd card, properly format it from my pc. But after I put my music files, it was on the "others" panel. Music player is playing fine, but it's bothering me. What could be a solution here?
