I've tried re-adding the songs twice now and every time it deletes a BUNCH of the songs. The only place I've noticed this was with Cascada. I have about 40 songs of hers that I tried to add and when I disconnect the phone from my computer and view the Music list, it only has 3, the same 3 every time. I'm putting the files on my SD card in MP3 > Cascada in their separate album folders. It keeps the folders and AlbumArt.jpg files but deletes the songs! Why is it doing this?
