Justin Bieber has revealed his frustration at his record label for their apparent lack of promotional support.

The singer has been releasing a new song each week for the last month as part of a new Music Mondays project, which is scheduled to run up to Christmas.

Its the first batch of new full material since his 2012 record 'Believe' and the Canadian took to Twitter earlier to criticise his label Def Jam over their promotion of his music.

Digital Spy reports that he posted: "Wish def jam would work harder on my project labels are shady."

However, the tweet was deleted soon after it was uploaded online. Bieber then wrote:

"Beliebers should work at my record label :) good promoting fans."

The 19-year-old's latest Music Mondays track came in the shape of 'Bad Day', which was released yesterday (November 4).

Other songs released through the campaign includes 'Hold Tight' and 'Heartbreaker'.

Bieber's busy schedule will reach a peak with the release of new film Believe on Christmas Day. Listen to 'Bad Day' below:
