Singer's record label are said to be shocked by the sheer volume of new songs

Beyonce is reported to have 72 songs in contention to appear on her new album ‘4’.

The singer, who revealed that her fourth solo album would be appropriately titled ‘4’ earlier this week, has delivered 72 songs to her record label in preparation for the album’s release.

According to The Sun today (May 14), staff at the singer’s label Columbia have been shocked at the volume of new material.

A source said: “Label staff leave Beyonce to get on with things, they tend not to interfere when she’s making an album. But they weren’t prepared for the sheer volume of material she presented to them. She’s clearly been very productive. Now they have the hard job of going through all the music and deciding what will make it.”

Collaborators on ‘4’ are rumoured to include Odd Future and Sleigh Bells. The singer released the first track from the album, ‘Run The World (Girls)’, last month – scroll down and click below to listen to it.
