Well I've just have the arduous task of compiling all my collection and correcting tags that I thought were fine (J3 disagrees) and adding album art.jpgs to each individual folder. My J3 has its 32gb memory filled so the album art additions took alone took 3 hours.
And after this I'm still finding that when I tilt the player to get the mosaic thumbnail view, that the goddamn pieces of art aren't showing up. I've noticed that for page 1-2, a few of the albums that begin with 'A' show up just fine, but the other 350 pages are just that annoying little quaver note.
Am I being stupid and missing something here? I've given this so much time and attention... why won't my J3 love me back?
