The headliner announcements - Coldplay, Muse and Adele - may have wrongfooted a few people, but seasoned fans know that Glastonbury is about so much more than the Pyramid Stage.
The first taste of the rest of the lineup emerged this morning, and there's already a plethora of acts, young and old, new and classic alike, to start getting excited about.
We've picked our top 10 to watch from the acts so far - be that in glorious sunshine, swamp-like mud, or just on your telly in the comfort of your front room.
Sigur Rós
The best live band on the planet, the Icelandic band have survived the departure of founder member Kjartan Sveinsson to remain an incredible act. It's nearly three years since their last album Kveikur, so expect some new material, some classics, and the most transcendental experience of your life - whether you're on the Class As or not.
Gregory Porter
The Californian jazz-soul singer possesses one of the most luxurious voices around, so make a beeline to see him in action at Worthy Farm. His new album Take Me To The Alley will be out by the time of the festival and if Holding On is anything to go by, it'll be a corker that you'll want to hear out loud.
Kamasi Washington
Kamasi has been a highly-respected jazz saxophonist and band leader for many years, but has been pushed into the spotlight by making a major contribution to Kendrick Lamar's landmark album To Pimp a Butterfly. Currently touring his 2015 debut album The Epic, expect his performance to be just that.
LCD Soundsystem
They may have only been gone five years, but the announcement of the live return of LCD Soundsystem was greeted with a reception that would make Jesus' comeback look like a support act. It's hard to imagine that they'll be anything other than a joyous riot of sound once again, so trudge through the mud and get over to see them.
Stormzy
With the UK grime scene gaining worldwide attention, building momentum all the while, now is the chance to see one of its leading lights in a small environment while you still can. Expect some hip hop royalty to be watching from the side of stage and an almost certain riot when he plays Shut Up.
Madness
Quite simply, what is there not to like about watching Madness on a summer's day? Led with style as always by Suggs, backed by some brilliant instrumentalists, including the legendary sax player Lee Thompson, and with a back catalogue of massive hits. If it's sunny, it'll be joyous, if it's raining, they'll cheer everyone up.
Lapsley
Adele might be headlining the main stage, but if you want to see who could be playing there in five years' time, get over and see her XL labelmate Lapsley, fresh from wowing crowds at Austin's SXSW festival.
Art Garfunkel
Paul Simon played the legends slot on a blisteringly hot day back in 2011 and now his erstwhile partner Art Garfunkel heads to Somerset to entertain the masses. Pay your respects to a true legend.
The 1975
They've just claimed a number one album on both sides of the Atlantic, and addressed their critics with the video for The Sound. Motormouth frontman Matt Healy was born to play to big crowds, and they head to Worthy Farm for a third time. The kids will all be there, so go and see what the fuss is all about.
ZZ Top
Rock is something of a lesser-spotted beast at Glastonbury, but this year's initial lineup announcement boasts Sheffield metallers Bring Me The Horizon, and the legendary Texan rockers ZZ Top. Don't hesitate, make your way to see them, and get ready for a blast of bluesy rock and roll.
