The BT on this device blows major chunks, i chave tried SD, HD and all sorts of headphones, you cant even put the playing in your pockt without the BT dropping left and right,,, dont buy this for wireless connectivity thats for sure!

If you have cover art in those folders, a number of players will skip or go blank for a second or more ,, remove the cover art on a folder that was skipping, update library... then try and play again. What happens?
