The Electric Picnic line-up divided the nation after it was announced at noon yesterday.
The XX will be headlining alongside A Tribe Called Quest and Duran Duran, but some people were left scratching their heads as to who these acts are.
In addition to these acts, Chaka Khan, Run The Jewels, Interpol, Father John Misty, and London Grammar will perform to thousands of music fans at Stradbally this September.
People were raging over the line-up with many complaining that they hadn't a clue who any of the acts were.
Others were indignant that the line-up was receiving such harsh criticism, and felt that the line-up was quite excellent.
Be confused no more, as here is your field guide to the main acts at this year's EP festival:
The XX
The XX are an unreal, award-winning band who have just released their third album, I See You.
The triad have an indie-pop, electronic-rock vibe which is difficult to describe.
Try listening to Intro and On Hold to get a feel for their sound.
A Tribe Called Quest
A Tribe Called Quest is an American hip-hop group that has been going since 1985, so they are like the OGs of hip hop.
Many Twitter users claimed not to know who the lads are, but they are responsible for classic anthems like Can I Kick It and We The People.
With a career spanning four decades, they are headliners for a reason.
They are also the subject of a critically acclaimed 2011 documentary film titled Beats, Rhymes & Life: The Travels of a Tribe Called Quest, so if you need any more information, you can find it there.
Duran Duran
Anyone whop was alive in the 80s or early 90s will know Duran Duran's sound from a mile away.
Responsible for amazing songs like Ordinary World, the new wave, synth pop band were formed in 1978 and have gone from strength to strength.
While they may have appeared to be the quintessential 80s boy band, the lads have always penned theoir own songs and their sound is still enjoyable today, as is all truly good music.
Chaka Kahn
The legendary Chaka Kahn will be gracing the stage at Stradbally this September.
The Queen of Funk has a career that has spanned five decades, and her soulful songs are totally iconic.
People may not recognise the name, but with songs like I'm Every Woman and Ain't Nobody in her repertoire, people will certainly recognise her sound.
Pete Tong
Pete Tong is bringing his Ibiza house classics to Electric Picnic, and it's going to be lit.
The DJ's history dates back to the popularity of acid house and one of the first waves of electronic music.
He's one pof the world's most coveted and recognised DJs, so his set is going to be class without a doubt.
Interpol
Famous indie rock band Interpol are legendary.
Rocking since 1997, the American band have an innovative indie sound that is beloved by fans of the post-punk revival.
Try Evil and Everything is Wrong for a taste of what they have to offer.
Run The Jewels
RTJ (as they are known by the cool kids) is an American hip hop group formed in 2013.
The band are responsible for epic tunes like Legend Has It and Talk To Me, and the group are renowned for their tireless charity work.

The band are difficult to categorise thanks to their somewhat ethereal sound, but rest assured they are amazing.
We think the line-up for Electric Picnic is pretty decent, but what do you think?
