Having a hard time with Mono MPEG2 Layer 3 file

Hi All

I just got my Meizu, it's very nice, but I'm having a hard time playing a file (a lecture) on it.

It's an mp3, here are the specs:

Kind: MPEG audio file
Bit Rate: 32 kbps
Sample Rate: 22.050 kHz
Format: MPEG-2, Layer 3
Channels: Mono
ID3 Tag: v2.3

In the Meizu, the name of the file is now "._lecture.mp3" while it is just lecture.mp3 if you look at the file on the computer.

Any ideas whats up?

Ok, so I got it to work by opening the file in BROWSER mode

Too bad the file doesn't work in the categories. Wonder why?
