Complaining about the discount
, pink's song still doesn't have a good chance to hit #1 in the next two weeks, the song hasn't entered the top 10 on the radio and is still gaining on streaming & on demand charts, I have no doubt it will hit #1, all she needs is just a live performance, the discount is to increase bruno's chances against Thrift Shop, because bruno is the closest behind Macklemore & Ryan Lewis to hit #1. You know their song is still #1 on iTunes combining the two versions.
Plus WIWYM has been selling +200k for weeks now.
The lead is humongous. 
, discounting is a strategy to promote a single or an album
Well actually, snatch Macklemore who has already snatched pink.
