music - How do I get this iTunes song on an Android device?

I want to buy this song, but it appears it's only offered on iTunes. I have no idea if it's DRM protected or not, I just want it on my Moto X.

• What are the most direct and straigtforward steps to determine if I can put this song on my device, and how I can do it?

I would like to purchase the song directly from my phone, but I have both a PC and a Mac
