Favorite Music Group is arguably one of the most popular -- if not one of the most difficult choices -- of the Kids' Choice Awards. This year, Maroon 5, One Direction, OneRepublic and Macklemore & Ryan Lewis are all competing for the coveted title. Which group is most deserving of the award?

Maroon 5 have still been riding the success of their 2012 album, 'Overexposed.' 2013 marked the release of their hit single, 'Love Somebody,' their fourth from the album. The overall success and chart position of 'Love Somebody' made 'Overexposed' the group's first album to spawn four Top 10 singles. That same year, the band embarked on an A-list summer tour with Kelly Clarkson, selling out numerous arenas.

One Direction are looking like the obvious winner for Favorite Music Group. Not only did they win the title last year, the adorable boy band (comprised of Harry, Zayn, Louis, Liam and Niall) are just as earth-shatteringly big as ever -- and their popularity (not to mention their devoted fan base of Directioners) is only growing. This past year, they released the album 'Midnight Memories' (their third in just two years!) which was an instant success, debuting at No. 1 in the U.S. This feat earned the guys of 1D a spot in music history, becoming the first band to have their first three albums debut in the top spot on the Billboard 200 charts. Pretty freaking impressive.

This past year was a big one for OneRepublic. The band, led by singer/songwriter/music producer extraordinaire Ryan Tedder, released their third studio album, 'Native,' in 2013. The album was, surprisingly, the first of the band's to debut in the Top 10 on the charts, landing the No. 4 spot. Their hit single, 'Counting Stars,' has received a ton of radio airplay, peaked at No. 2 on the U.S. Billboard charts and came in at the top spot on countless international charts as well.

Not to be outdone, Macklemore & Ryan Lewis had quite the whirlwind year. Their debut album, 'The Heist,' spawned multiple hits, including 'Thrift Shop,' 'Same Love' and 'Can't Hold Us,' and the duo received worldwide success and stardom. At the 2014 Grammy Awards, Macklemore & Ryan Lewis cleaned up, winning the titles of Best New Artist, Best Rap Album for 'The Heist' and Best Rap Performance and Best Rap Song for 'Thrift Shop.' But that's not all: The group made history when 33 couples got married during their 2014 Grammy performance of 'Same Love.' Not everyone can say that.

Which group do you think will take home the title of Favorite Music Group? You can vote for Maroon 5, One Direction, OneRepublic or Macklemore & Ryan Lewis once an hour until the poll closes on March 29 at 7:59 PM ET.
