Beyonce stuns record bosses!

Singer Beyonce has stunned her recording bosses, as she delivered 72 tracks for her latest album. With that whopping number, the label staff are in happy headache over picking the right numbers which fit the album.

“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 the album," dailystar.co.uk quoted a source as saying.

The 'Crazy in Love' star has joined hands with American pop and R&B singer-songwriter Ne-Yo, Switch, Sean Garrett and Sleigh Bells' Derek Miller for the upcoming album. It is said that it would hit the store by this summer.
