basically what i think about this indie speculation: I don't think she is abandoning promo at all, just that she won't visit these irrelevant shows like gma etc but rather just perform at shows that give bigger push.
I don't understand this daylight / nighttime thing
Gaga's performance would be during the daylight cause of the different timezones. People prefer performances in nighttime like Katy's, just cause that way the stage colors are brighter and better.
