I have a Mac computer, an ipad, and an android phone. I buy and have been buying all my music from iTunes. I used to have an iPhone so when I bought something from iTunes on one device, it appeared on all of the other devices without cables or transferring anything. I just want to know how I can get my new iTunes music to automatically download on my android phone if possible, and if not, how do I do it with the least amount of work? Thanks.
