Hair is one of my most anticipated tracks. I don't see why she can't just make Edge of Glory the third single. It's had an incredible response and is selling well. Hmmm... I can understand why she'd wait to release MTN as a single.
I think some of you are getting too hung up on the chart performance of Judas. Remember that singles exist for the sole purpose of selling the album that they're on. Yes, they spent money on the Judas video, but not for the purpose of selling Judas, but to sell the album. That's all singles are...promos to try and get people to buy the album. That's where the money is made, not singles.
So even if Judas has peaked(which it probably hasn't actually), it will still have done its job in helping to sell the album. Those 15 million views on YouTube is a RESULT.
Hair...? I thought its going to be the 2nd Countdown-Single? There should be some time (a couple of months) between being released as a Promo and as a official Single, right? I'm confused.
