Music

There are a ton of ways.

1. (Cloud) Google Play Music. Download the Google Music Manager for your computer, point it to your iTunes library, and wait a few days for it to upload all your music. Then open Google Play Music on your phone and play whatever you want from the Innernets.

2. Get a big-ass SD card, copy all the folders of music from your computer that will fit on it, pop it in your phone and use the stock music player (or PowerAmp, etc.)

3. Use DoubleTwist to sync your iTunes library to your phone (might run into space issues if you have a large collection).

4. Use Android File Transfer, WiFi File Explorer, or AirDroid to move specific music files to your SD card.

Hope one of those suits you.
