Why are you transferring music this way? What do you play music with? If you use the Google player (which I recommend) your going about putting music on your tablet the wrong way.

A much faster and easier way is to download Google music manger (its from Google and is 100% safe) and it uploads your entire library to the Google cloud. After it uploads everything for the first time it will only upload any new music you get after that.  You can also select certain folders.

After that you sync your Google music app and all your music will be there. You can either store the music or choose to download any of it to your internal storage for offline listening. Its really neat the way it all works and the nest part is that its free. It allows you to easily choose what music you want to keep on your tablet when you have memory concerns without a bunch or connecting and unconneting with your computer.

I'm just offering an alternative.

Good idea however severely limited in storage and doesn't support lossless, only mp3. Plus letting Google have access to my 2tb music collection doesn't sound like a good idea.

Just came through today for me.
