U2 have joked that they might release their next album by putting CD copies under people's pillows while they're sleeping.

The band initially issued their 2014 effort 'Songs of Innocence' digitally to iTunes users free of charge before it got a physical release. Speaking to Rolling Stone, guitarist The Edge said they aren't sure how their follow-up will be distributed yet.

The musician confirmed that 'Songs of Experience' is well on its way to completion, with the record expected to land later this year. Speaking about how it will be released, The Edge said:

"My plan is that Bono and I would sneak into everyone's house and put a CD under their pillow [laughs]. But unfortunately, that doesn't seem to be getting much support from the rest of the band. But, no, again, it's quite interesting the way music distribution and promotion and marketing has sort of been thrown into turmoil over the last number of years. What seemed like the most cutting-edge and innovative ideas six months ago no longer seem novel or groundbreaking. Also, I'm aware that sales of vinyl records are going through the roof. It's just crazy to see that. That speaks about so many things about what the artifact, the object of a vinyl record signifies to people versus a digital download, a file. People, in the end, have an emotional connection with a great record and with the artist.

"A digital file is … Look, convenience is wonderful. If I'm being honest, I still have my vinyl collection, but I use digital files 90 percent of the time. But I would never give up my vinyl. And so there's a need for both, and I find that kind of reassuring that in the midst of convenience being king, there's still this deep, emotional connection that people have with the body of work that is an album. So who knows? We're still trying to figure it out like everyone else.

"What I find heartwarming is that music culture and music is still at the forefront. People are enjoying it and reveling in it and turning to it for all kinds of reasons. I'm interested to see if in this new post-truth world, music sort of reconnects with the activist-protest thread that it had for so many years and seems to have lost recently. I think that aspect of music has always been, to my mind, an important, crucial part of what drew me to it, and why I think a lot of people are drawn to it.

"So I feel that this is a moment where music might go through a kind of renaissance of a kind and I'm very excited to see what young kids in their garages across North America and Europe are going to be writing about and releasing over the next number of years. I think it's time to get back to some of that."
