London: Beyonce reportedly stunned her record label bosses when she handed over 72 new tracks for her upcoming album.
"Label staff leave Beyonce to get on with things, they tend not to interfere when she`s making an album," dailystar.co.uk quoted a source as saying.
"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 the album," the source added.
Beyonce is expected to release her next project, titled ‘4’ by this summer.
