Rapper Tech N9ne has shed light on the song that fuelled the Eminem-Machine Gun Kelly (MGK) feud fire.
Speaking to HipHopDX, Tech N9ne said he had originally been oblivious to the fact MGK used N9ne's song 'No Reason' to diss Eminem and was shocked when people came out saying he had known and supported it.

"I was blindsided. I didn't know it was about Em," he said.
In the song, MGK raps "to remind y'all you just rap, you're not God/And I don't care who got bars", a reference to Eminem song 'Rap God'.
Eminem responded to that in his song 'Not Alike' from new album Kamizake, rapping "next time don't use Tech N9ne to come at me with a submachine gun".
MGK apparently later apologised to Tech N9ne.
"MGK called me the next day and was like, 'Tech man, I'm sorry man. I would've given you the Rap Genius breakdown at the beginning to let you know,'" he said. "He was like, 'You know, we've been going at it for a while over his daughter.'"
MGK tweeted in 2012 that Eminem's daughter, Hailie, then aged 16, was "hot as f**k", causing controversy and criticism from Eminem.
Tech N9ne clarified he didn't know there was still a feud between MGK and Eminem, and noted things were good with Slim Shady, whom he had explained the situation to.
The feud has seen a month of back-and-forth diss tracks between Eminem and MGK. After 'Not Alike', MGK responded with the track 'Rap Devil', in which he says Eminem is a bully acting like a baby and is so old "he can't stand up". Eminem called the song "pitiful".
Just days later, Eminem continued the feud with 'Killshot', in which he again insulted MGK's lyrical ability and album sales. Eminem was the best-selling artist of the 2000s in the US.
'Killshot' has broken the YouTube record for biggest hip-hop debut, with the song's video reaching more than 36 million views in 24 hours. The video is also the third biggest video debut in YouTube's history.
