Fifth Harmony vs. BIGBANG: 2017 Summer Fan Showdown [Round 1]

Summer Fan Showdown is a month-long competition on PopCrush to determine this summer's most dedicated fan base.

The battle starts now: place your vote between Fifth Harmony and BIGBANG. This round ends on June 9 at midnight.

The girls of Fifth Harmony have come a long way since the days of X Factor USA back in 2012, evolving from cutesy sleepover sing-alongs like "Me & My Girls" and "Miss Movin' On" to more mature bangers like "Worth It" and "Work From Home." And even though they're now down one member, the girls are about to show us that they're still so much better together. The Harmonizers have kept Lauren, Ally, Normani and Dinah Jane afloat for years. Will they push the girls into Round 2?

And then there's BIGBANG: the long-running 5-piece boy band, which first debuted in 2006, have since gone on to become one of South Korea's defining pop acts. After performing their Big Bang The Concert: 0.To.10 Final In Seoul encore shows at the top of 2017 to wrap up their 10th anniversary activities, the troupe is currently down one member as T.O.P.'s required military enlistment begins — but they're still touring Japan, anyway. Will the V.I.P. keep the BIGBANG boys moving on to the second round of the Showdown?

The battle starts now: place your vote between Fifth Harmony and BIGBANG. This round ends on June 9 at midnight.

This round is over. Vote in Round 2!
