“Resistance Is Useless” is the 8th track of the Sing Me a Lullaby, My Sweet Temptation.
It’s a song that reminds the fans that Boy$ only changed their style, not their roots like Ruby says in the last lines of the song

Still in that 7th, ain’t nothing has changed
Still wearing FTP fits to the grave
Still fuck the fame, fuck the pressure and pain
Only thing changed is I cut off my mane
