Install Zedge
Just use Audacity on the computer to do it. That's what I do. Then you can do fade in and fade out for the ringtone. Or other audio adjustments. Audacity is the best free audio editor for Windows.Doesn't look like Ringdroid will do it, at least not with any song that I've marked for download to my device.
If you jump through the hoops of downloading it as an mp3 file on your computer and then transfer that file to your device Ringdroid should be able to work on it then.
Looked at Zedge once, but way too much overhead for what you get. For me anyway.
Overhead? Its all free. If free is overhead then what else is left.
Overhead is all the crap that comes with the app.

So I purchased a song on Google but I don't see any option to make it a ringtone?
