The poor performance of U2's last few songs has disappointed the band.
U2 have expressed their displeasure at their last record producing few hit singles.
Speaking to the Associated Press, frontman Bono attributed the poor performance of Get On Your Boots, Magnificent and I'll Go Crazy If I Don't Go Crazy to the band not being in the right mindset to write a commercially successful record.
"We felt that the album was a kind of an almost extinct species, and we should approach it in totality and create a mood and a feeling, and a beginning, middle and an end," he explained.
The singer also claimed that the record could have been too hard for pop-loving music fans to access.
U2 bassist Adam Clayton also told the news provider that the concept of the music lover - or someone who buys albums for the sheer pleasure of listening to them - is "outdated".
Earlier this month, Bono praised US president Barack Obama in an opinion piece he wrote for the New York Times.
The singer said that Obama's dedication to ending world poverty justified him receiving this year's Nobel Peace Prize.
