K-pop boy group BTS is gradually building up anticipation for the group's comeback later today.
On February 21, BTS dropped a 30-second preview of its comeback title track 'ON' on the group's official TicTok account.

'ON' is the title track of BTS' upcoming fourth full album 'MAP OF THE SOUL : 7', which is set to be released later today at 6PM KST.
The 30-second
snippet features the pre-chorus of the song, with the lyrics that says:
Hey na na na
You need to be crazy in order to not go insane
Hey na na na
I throw all of myself into two sides of the world
Hey na na na
Can't hold me down cuz you know I’m a fighter
The beautiful prison that I walked into on my own
Find me and I'm gonna live with ya

Of course, hundreds and thousands of ARMY (BTS' official fan club) swarmed TicTok at a time that they actually made the application crashed and unresponsive for a while.
In less than an hour since the song preview's initial release, thousands of fans have already created their own TicTok videos to build the hype towards the upcoming release.

Meanwhile, BTS is scheduled to hold a global press conference on February 24 to talk more about 'MAP OF THE SOUL : 7'.
