I bought an Android ringtone at Google Play Store on my PC. How do I transfer it to my phone and select it as my ringtone? The song is Money Talks by ACDC. I bought it at this link: Google Play link to buy ringtone
Follow this -
Menu > Settings > Sound > Phone ringtone > Sound picker > Music library > Select tone
Remember, this is the general way to pick a tone in Xperia (Sony) phones. Terminology may be different in other devices.
