I saw at the Rockstar social club some people have music from the radio attached to their photos. How do you do that? Is it a PC only feature?
When you view your gallery you can select a pic to edit, I haven't done it myself but there is an option to add a song.
All I see is an option to change the title.
This seems to be a random added feature. I have one photo in my gallery on social club which apparently also has music added to it. It looks like they added it as some kind of advertising.
