Happy X3 user, skim this thread from time to time, don't have the time/patience to review all 429 pages. Have similar tagging issues. Haven't gone back to retag with any software, maybe I should. Have a mix of FLAC, Apple Lossless, and WAV for the most part. I find I can't rely on Artist, Album, or Genre, I generally go in through the file section and find the music, most of which is on my memory card. I generally rip my own CD's, initially did this with JRiver, used the program to send it to the memory card. Things wound up there badly named, out of order, annoying. That's when I started using iTunes, at least the albums stay in proper order. I rip, then find the files in Windows Explorer, then drag them to the microSD card. I'm sure there are better ways to do this...maybe I just have to get used to using some tagging program to clean it up. Do manage to get to everything by file search, and think the sound is really nice (mostly use it with line out to ALO National Amp). Tips would be appreciated (read the whole thread would not be a helpful tip, even if it's true). Thanks.
