San E disses rapper B-Free in his new release, 'On Top of Your Head'

In the newly dropped short version of his MV for the pre-release track, "On Top Of Your Head," San E directly called out rapper B-Free, saying that no matter what B-Free says, San E will still come out on top.

In 2014, B-Free dropped a fierce diss track, "My Team," where he dissed San E for being a "retarded rapper," a loser, who is afraid to admit that he dissed anyone.

It took a while for a response to B-Free's attack but San E responded accordingly and rapped, "You ask why I say I didn't diss when I did, but you don't know me. I'm the type to reveal names (B-Free). Oh, congratulations on winning. Hey do you know a song titled, 'Hot Summer'?" San E then goes on to sing an excerpt of f(x)'s "Hot Summer," (referencing B-Free's song of the same name) before claiming that he is forever on top of B-Free's head.

In the past, B-Free garnered much attention for his harsh words towards BTS' Rap Monster and Suga during a joint appearance on 'Kim Bong Hyun's Hip Hop Invitational 1st Anniversary Broadcast.'

At the time, B-Free explained via Twitter that it was just his nature to poke fun of men who wear makeup, "like a girl," and dance like Lady Gaga. The rapper also continued the feud with BTS fans by sarcastically retweeting hate comments.

Though it is within the nature of the hip hop genre and rap to diss and get dissed, B-Free seems to be much more aggravated when it comes to mainstream hip hop.

Your move, B-Free.
