First social media shots fired by New York Red Bulls in #NYCSoccerWarz | SIDELINE

Round 1 in the #TopBantz battle between the New York Red Bulls and New York City FC goes decisively to the team with "some history." 

That photo is of the song list from NYCFC's largest supporters group, the Third Rail. If you want to know why it went a little bit viral on Sunday evening, check out the song at the bottom right. And also check out the always-fun #NYCSoccerWarz hashtag on Twitter.

RBNY host NYCFC on Sunday night (7 pm ET; FoxSports 1) in the first-ever on-field meeting between the two clubs.
