Who knows if Eminem will be able to get a #1 on a debut week based on sales, airplay and streaming? He started back in the 90s, he sold quite a great amount of albums and singles back then and when the music industry became digital, he showed he could still sell a good amount of albums and singles, see Not Afraid, Love the Way You Lie and The Monster. I should mention Lose Yourself as well, which is one, if not his best catalog selling single. Oscar winning song has sold five million digital copies despite being released before iTunes blew up. Stop being so pressed about everything that comes close to Taylor, I bet she's fine with it, she's humble and ain't cocky and annoying like you.
