They load and work, they just don't show up in categorized browsing due to lack of ID3 tag recognition. File name shows up though so you know what song it is, but all information otherwise does not.
So as of right now, I listen to my ALAC/AAC songs by manual file browsing. They are already all in artist and album folders organized as like on my PC so its not that hard.
For example, I have a Folder in 'Browse Files' (and on SD card) called Linkin Park.
I scroll all the way down there( 5-10s) and then click and I am met with all the folders I already made on the computer. They are teh album names, then I click again and voila! Songs. Although only their file names(and subsequently title name) are featured. All id3 tags are nada.
