Ive downloaded all the apps, I have a Verizon tablet, it won't work no matter what I do!?! How do I move my music to my SD car

What won't work - the whole tablet? If the tablet works at all, go into Settings>My Device>and tap Build No. seven times. That adds the option of Developer Options to the list and one of those options is USB Debugging. Tap to enable that and connecting to a PC becomes a lot easier

If you can't do it on the tablet, use a Windows PC to download Android Commander and install it on that PC. Connect the phone to the PC and run the programme and you should see the contents of the tablet in one windows and the folders of the PC in the other. From there on, it's a simple drag and drop process.
