shows all my data for songs.. i spent days/weeks in total through the past tagging most of my music(90gbs) though.. adding correct info, embedding album art, and getting everything right..
try MP3tag editor(enclosed), its a desktop program(free) and its great.. just put your sd card in your PC/lappy add your "MUSIC" folder to the directory and go through and check your music out... simply having an "folder.jpg"(album art pic) doesnt make it compatible with every player.. one needs to embed images to mp3s, then theyll show on everything..
so heres the desktop app though to check out your music files..**decided to go with a link so you can check it first yourself- i love this program though**
