Those lines in Cold Wind Blows are kinda strange:
"This shit is on cuz you went and pissed me off...but take a look at Mariah the next time I inspire you to write a song."
Don't know whether those lines related to the Elton John line or not, but if they did...
Things Elton John could have done to piss Eminem off:
1. He grabbed Eminem's cock.
2. He took the girls out for ice cream without Eminem's permission.
3. He wrote a new song about a man who pops pills and is a terrible father and husband and makes shitty music.
