I originally used winamp, it played m4a wma and mp3 files, whereas windows media player wouldnt play m4a files. Eventually I tagged all my music and realized I would need to convert the m4a's. It took too long, so in the end I just deleted them all, and switched to windows media player which organized my music rather quickly, but I had trouble changing things my own way for more obscure bands and putting in my own album art and making it stay there. I just got your stuff today. WOW, it takes 3 seconds to update an entire album, the album artwork is better, and even if I cant find the artwork, I can add it in myself without any hassle. and I havent been kicked out once, and it plays the mp3's that windows media player "can't read"
