I'd quite like "Need Your Body" as the single title. It's commercial enough and could be good. Assuming it's a title or an actual lyric from a song. Jo tweeted it so, it's a possibility.
Controversy isn't bad. But its gotta be good controversy. The meat dress was shocking and at the same time interesting. People wanted to know about it. It put some people off but that's just how controversy works. It keeps people talking. Doesn't mean she should over do it though.
And yeah that need your body thing Jo tweeted was from a dance song back in the 90s not sure of that's really ARTPOP related.
as much as I love it when she does controversial stuff, but I think the title of the first single should be simple enough that everyone loves it, we all know what happened when Judas came out!
