The band - who will perform at BBC Radio 1's Big Weekend in Glasgow today (May 24) - were hoping for more of a hip-hop left field option following Jay Z's controversial headline set back in 2008.
"I personally don't think [Metallica are] a very good booking," guitarist Jamie MacColl told Digital Spy at Big Weekend. "I think the lineup is a bit disappointing generally.
"My ideal line-up was Prince, Fleetwood Mac and Kanye West. I wanted a left-field Jay Z option again. I'm sure it will be great though."
Asked if they are looking forward to their appearance at Worthy Farm, he added: "Yeah, we've got a good slot and The Other Stage is probably the best stage at the festival."
Bombay Bicycle Club claimed their first number one album back in February with their fourth collection So Long, See You Tomorrow.
Meanwhile, Coldplay, Katy Perry, One Direction, Kings of Leon, Kasabian, Jake Bugg and Lily Allen will play this year's Big Weekend in Glasgow.
The two-day music event will air on BBC Radio 1 and 1Xtra across the weekend, as well as streaming on their official website and highlights on BBC Three this evening.
