Muse: They were born to headline festivals and Glasto is the daddy of them all. Could they top off their last two headline slots?
Fleetwood Mac: It's been rumoured since forever, so it has to happen. There's talk of new material, so maybe 2016 will be their year?
Queen: Brian May says they are 'interested' in headlining Glasto with Adam Lambert - so are we. They've got enough legendary hits and prowess to blow all other Sunday night headliners in history out of the water.
Rihanna: With her eighth album on the horizon, could she be next year's wildcard? The next step from Beyonce, Jay Z and Kanye? Petition your hearts out, we think she'd be pretty decent.
Madonna: The same goes for our Madge, providing she keeps her cape at home. It's a long fall from the Pyramid Stage.
Paul McCartney: With no signs of retiring, Macca will never stop touring, surely? Either way, he's not been at Glasto since 2004 so is probably due a return in the legends' slot.
Taylor Swift: Eavis says he 'would love' for her to play, and she's the biggest pop star on the planet so why not?
Prince: It just wouldn't be Glastonbury without a rumour of the Purple One now, would it?
The Killers: Brandon Flowers may be touring his stunning second solo LP The Desired Effect right now, but the band are already in talks on new material. Surely we can hope for a massive comeback of sorts in 2016? Perhaps it's time for them to outdo their divisive 2007 headline performance?
Radiohead: They're Glasto veterans, but haven't headlined since 2003. It's been a bloody long time coming, and they're said to be making new material as we speak. This would be a pretty historic set to see off Glasto before its fallow year.
Coldplay: They've headlined so many times that they're basically the Glasto houseband. Their 'final' album, A Headful Of Dreams, is coming soon - Glastonbury sounds like the perfect goodbye, surely? Rumour has it that Michael Eavis has confirmed it to 'close sources'.
Oasis: The rumour mill continues. Have they buried the hatchet or not? Is Liam reviving the band without Noel? Who knows what goes on behind closed tours? But if Noel finishes off touring his world-conquering solo album Chasing Yesterday, who knows what next year could hold? They're currently among the bookies' favourites.
The Strokes: Their 2015 shows and glorious British Summer Time set at Hyde Park proved that they've still got something special, and the world is hungry. Maybe by next summer they have put all drama to bed to storm back with some new material? The Glasto Pyramid Stage is crying out for them.
Foo Fighters: Early reports suggest that the Foos have already signed up to play next year, and the bookies too have named them favourites to come back and make up their disappointing no-show this year.
