FS#13059 - MP3 Codec decoding has artifacts

When playing music, I can hear codec errors in the music. It occurs every time on a certain song, and other songs that are smaller in file size, it does not occur on, but occurs on the next one. I believe it is a buffering issue, and makes the music unlistenable. I used the daily on 10/21/2015

On 320kb/s MP3s it occurs much more often, and 128kb/s MP3s it occurs less often, but when it occurs its a series of glitches that distort the music.

I am sure its not the MP3s themselves, because it doesn't occur in the official firmware, and when I rewind it, it does not make the same sound until later. It has a very prominent 'glitchy' sound and later it changes the speed of the song.

I replaced it with the 3.1.3 MP3 codec, and the same glitch occurs.

I do not have a line out so its made through the speaker, but the problem is so bad that you can hear it very clearly.

The MP3 was 320kb/s

Memo is the glitchy one, and Memo-1 is it being played correctly.

Sorry I cannot edit my post.

I noticed that when I was watching the playback bar, around the time that it would skip, the playback bar would go to the end, then go back to the location where it was playing. The music is playing while this is occurring and then I can hear the glitches.
